enantiospecific total syntheses of structurally diverse natural products such as machaeriol-D, Delta(8)-THC, Delta(9)-THC, epi-perrottetinene and their analogues. Synthesis of both natural products and their enantiomers has been achieved with high atom economy, in a protecting group free manner and in less than 6 steps, the longest linear sequence, in a very good overall yield starting from R-(+) and S-(-)-limonene

First enantiospecific total syntheses of the cannabinol‐skeletal carbazole alkaloids murrayamines‐O and ‐P isolated from root barks of Murraya euchrestifoli, have been accomplished by highly diastereoselective, Lewis acid catalyzed coupling reactions of commercially available monoterpenes with carbazole derivative, which in addition to confirming the structure also established the absolute configuration

Enantiospecific total syntheses of (+)‐hapalindole H and (−)‐12‐epi‐hapalindole U as well as the formal syntheses of (+)‐hapalindole Q and (+)‐12‐epi‐fischerindole U isothiocyanate have been described. Key steps of our approach feature expedient, highly regio‐ and diastereoselective Lewis acid catalyzed Friedel–Crafts reaction of indole with cyclic allylic alcohols and intramolecular reductive Heck
