摘要

Macrocycles containing two o-iminoanilino units undergo stereoselective C-alkylation on treatment with Grignard reagents or lithium alkyls to give the meso-dialkyl-substituted macrocyclic tetra-amines. ... As part of a much wider programme1 of design and synthesis of tetra-azamacrocycles we have recently considered syste- matic methods for the preparation of a range of macrocyclic te t ra-ami nes which incorporate a1 kyl su bst it uen ts. Often the most troublesome ...
