Industrial microorganisms have been improved mainly by mutation and selection for their productivity, but recent development of gene manipulation would offer more effective tool for microbial breedings. Since the primary gene products are polypeptides, the gene manipulation techniques have been mainly applied to produce human peptide hormones, interferons and enzymes. These polypeptides have been expected to be useful for therapy of human diseases in near future. The technique will be available also to improve biomass production including microorganisms and plants. Further application is planned in the field of chemical industry, such as the conversion of ethylene to ethylene oxide. In addition, this technique would be developed as tolls for breeding of industrial microorganisms, especially in Japan.

Recent advances in the synthesis of useful organic compounds by enzymatic method are described. Various L-amino acids were synthesized by multifunctional pyridoxal enzymes; D-amino acids, especiall D-phenylglycine derivatives, by dihydropyrimidinase, purine arabinosides by nucleoside phosphorylases, insulin by proteases, steroid hormons by oxygenases, semisynthetic penicillins by penicillin acylase, and coenzyme A through biosynthetic pathway with pantothenic acid and L-cysteine under the coupling with ATP-generating system.The described enzymatic methods are simple and the most economical processes to date for the industrial production of these useful compounds.

Applications of prenyltransferases to the organic synthesis of some biologically active compounds are described.Trishomo-15, bishomo-16 and homo-farnesyl pyrophosphate 9, whose carbon skeletons are the same as those of the insect juvenile hormones, JH 0, JH I, and JH II, respectively, are synthesized by the action of farnesyl pyrophosphate synthetase of pig liver.The stereospecific C-C bond forming reaction of farnesyl pyrophosphate synthetase was efficiently utilized in the asymmetric synthesis of the stereoisomers of faranal, a trail pheromone of the Pharaoh ant, to establish the absolute configuration of the pheromone.The distribution of carbon chain length of polyprenyl pyrophosphates synthesized with solanesyl pyrophosphate synthetase of Micrococcus luteus can be controled artificially by changing the Mg++ concentration of the reaction mixture.

When N-(1, 2-diacetoxyethyl)-phthalimide was pyrolyzed under high temperatures, it was found that the dehydroacetoxylation proceeded in a highly selective manner to give N-(2-acetoxyvinyl)-phthalimide.Pyrolysis of N-(1-acetoxy-2-bromoethyl)-phthalimide at 537±3 produced N-(2-bromoviny1)-phthalimide.

Acaricide “Citrazon” and herbicide “Alloxydim sodium” were invented by Nippon Soda Co., Ltd. in the studies on the applications of hydroxamic acid derivatives for pesticides. “Citrazon” is a systemic acaricide for the control of Panonychus Citri and P. ulimi. While, “Alloxydim sodium” is a selective herbicide for grassneed having no phytotoxity effect towards broadleaf crops.These compounds have entirely unique chemical structures compared with the ordinary pesticides. Therefore, many investigations were required for the establishment of the manufacturing procedures, especially of allyloxyamine, ethoxyamine and 2, 6-dimethoxybenzoic acid.At the same time, new effective catalysts in acylation and alkylation were found out.

1, 3-Dithiolium and 1, 3-oxathiolium cations are positively charged 6π electronic species and the C-2 carbon which has the largest positive charge density is bonded with two hetero atoms leading to high sensitivity toward nucleophiles.We have investigated the aromaticity of 1, 3-dithiolium cation and chemical behavior of the both cations toward nucleophiles as well as synthetic application of biologically active compounds.In light of our results, dithiolium cation forms an interesting class of versatile compound in view of its nonbenzenoid aromaticity and oxathiolium cation exhibits a high reactivity toward a variety of nucleophiles providing novel heterocyclic compounds and their precursors depending on the nature of the reagents and the reaction conditions. Thus, oxathiolium cations proved to be highly versatile synthetic intermediates.

In recent years, α-chlorosulfides have been utilized as very useful synthetic intermedites. Firstly, in this article, the preparation methods of α-chlorosulfides are reviewed, and the critical points of the preparative reactions are summerized as follows : (1) selectivity of degree of the chlorination, (2) α, β-elimination of hydrogen chloride, (3) cleavage of C-S bond of sulfides, and (4) regioselectivity of the chlorination. Secondly, many types of the reaction of α-chlorosulfides are introduced together with each typical application in organic synthesis, classified in three groups, (1) the reactions with nucleophiles, (2) the reactions as electrophiles, and (3) miscellaneous reactions.The scope and limitation of the synthetic utility of the reaction of α-chlorosulfides will be clarified in this review.

This article is concerned with the uses of chiral synthetic polymers as catalysts in asymmetric reactions. The polymer catalysts are classified into two groups : (a) polymers with chiral main chain; (b) polymers with chiral side chain. The asymmetric reactions discussed are hydrocyanation, addition of thiols to C=C, addition of methanol to C=C=O, hydrogenation, Michael reactions, phase-transfer reactions, hydrosilylation, and hydroformylation. The emphasis here will be on the polymer effects.

The characteristic flavours in plant-, leaf alcohol, cis-3-hexenol, and leaf aldehyde, trans- 2- hexenal, are widely distributed in fresh leaves, vegetables and fruits and are responsible for the odor characteristic of the leaf. Also, both are found in some insect excretions as functioning attractants and repellents.The investigation of leaf alcohol has been carried out by Takei and Ohno et al. since 1938; from 1957, we have been studying leaf alcohol and leaf aldehyde from a number of angles : synthetic chemistry, natural products chemistry, and plant biochemistry.Recently, we focused our attention on the biosynthesis of leaf alcohol and leaf aldehyde and have demonstrated the biosynthetic pathway using Thea sinensis leaves. We know now that leaf alcohol and aldehyde are produced from cis-3-hexenal. This C6-compound, cis-3-hexenal and the C12-compound, 11-formyl-cis-9-undecenoic acid, are biosynthesized from linolenic acid by enzymatic oxygenative splitting through the addition of oxygen to the double bond between C-12 and C-13. This C12-fragment isomerizes to give 11-formyl-trans-10-undecenoic acid, traumatic half aldehyde, which is known as the “Wound Hormone”.

The effects of polyethyleneglycol dialkyl ethers as solvents in the reaction of potassium 3-aminophenoxide with isopropyl chloride were studied. The reactions using the polyethyleneglycol dialkyl ethers as solvents gave O- isopropylated 3-aminophenol in higher yields than using small amounts of dibenzo-18- crown-6 or the polyethyleneglycol dialkyl ethers as solvents.

“Synthetic Methods of Organic Chemistry” by Theilheimer is well known as secondary sources of organic reactions. In 1975, a British company, Derwent published “Journal of Synthetic Method” as a part of Chemical Reactions Documentation Service (CRDS) system.On-line retrieval of CRDS by telephone line has been available in Japan and even Theilheimer can be retrieved on the same system. In addition to the above, in 1979, ISI published “Current Chemical Reactions” in U. S. A., thus secondary sources of organic reactions have been gradually developed.The present article reviews secondary sources which have seldom been reported before.
