Stereoselective Synthesis of New Conformationally Restricted Analogues of a Potent CGRP Receptor Antagonist
摘要:
A stereocontrolled racemic synthesis of conformationally restricted analogues 2a and 2b of a potent CGRP receptor antagonist 1 by novel functionalization of 2-substituted octahydropyrido[1,2-a]pyrazin-6-ones is described. The new diastereoselective LDA-promoted α-nitration of intermediate lactams established the required trans-configuration in the desired products.
