This review involves the synthetic studies on the salamander alkaloids isolated from an animal venom in the skin gland of Salamandra maculosa <I>Laurenti</I>. Syntheses of three groups of the alkaloids, one with a bicyclo-oxazolidine system, one with a carbinolamine system, and another with a pure 3-aza-A-homo steroid system, are discussed separately. It will be emphasized that the synthetic works described herein made a considerable contribution to the structure analyses of this field of alkaloids and earlier proposed structures based on X-ray and spectroscopic analyses have been changed step by step. Regio and stereospecific syntheses of the alkaloids are mainly discussed in connection with the construction of the bicyclo-oxazolidine system of the major alkaloids and with Beckmann rearrangement of steroid 3-ketoximes for the syntheses of the other alkaloids.
