The book discusses the process of designing total syntheses; the biogenetic-like steroid synthesis, including cyclization of terminal epoxides as well as the total synthesis from nonepoxide precursors; and the synthesis of equilenin, estrone, bisdehydrodoisynolic acid, 18,19-bisnorprogesterone, 19-norpregnanes, and heterocyclic steroids. The text also describes the application of ABD intermediates in the Torgov synthesis; the synthesis of carbocyclics and thiasteroids; and the synthesis from p-anisylcyclohexanes and from C-5, C-8 bridged intermediates. The synthesis based on the type of reaction used in the condensation of the A fragment with the CD portion, as well as the methods of total synthesis in the preparation of 8-azasteroids and 8,13-diazasteroids are also considered. The book further tackles the synthesis of epiandrosterone, cortisone, aldosterone, 3β-hydroxy-5α-pregnan-20-one, latifoline, conessine, and ring C aromatic steroids; the synthesis of trans-benzohydrindane derivatives and other common derivatives; and the synthesis of CD intermediates. Chemists, biochemists, and people involved in the study of steroid total syntheses will find the book invaluable.
