摘要

Careful choice of the N-protecting group provides crucial conformational control, allowing ring-closure to the indole 3-position in the late stages of the synthesis of ajmaline alkaloids; the choice of protecting group and reducing agent can also provide access to either the natural or epi configuration at the indole 2-position.
