WebDec 1, 1998 · Enantioselective total synthesis of taxol has been accomplished. Coupling reaction of the optically pure A-ring hydroxy aldehyde with the aromatic C-ring fragment followed by Lewis acid mediated eight-membered B-ring cyclization gave the desired ABC endo-tricarbocycle. The C-ring moiety of this product was reduced under Birch conditions … WebThe total synthesis of haliclonin A was accomplished. Starting from 3,5‐dimethoxybenzoic acid, a functionalized cyclohexanone fused to a 17‐membered ring was prepared through a Birch reduction/alkylation sequence, ring‐closing metathesis, intramolecular cyclopropanation, and stereoselective 1,4‐addition of an organocopper reagent to an …
