Synthetic Studies on the Picraline-Type Indole Alkaloids-I: Improved Synthesis of C-Mavacurine-Type Compounds and a New Skeletal Rearrangement in a Corynanthe-Type Derivative.
Synthetic Studies on the Picraline-Type Indole Alkaloids-I: Improved Synthesis of C-Mavacurine-Type Compounds and a New Skeletal Rearrangement in a Corynanthe-Type Derivative.
An efficent synthesis of the C/D ring-cleaved compounds (13S and 13R) from hirsutine (7) and their transformation into three different type of products, 8 (C-mavacurine type), 18 (isopleicarpamine type), and 22 are described
