Abstract

Azatryptophane homologues, 4‐(imidazo[1,2‐a]pyridinyl‐3)‐ 9a‐9f and 4‐(imidazo[1,2‐a]pyrimidinyl‐3)‐4‐oxohomoalanine derivatives 9g‐91, were prepared from N,N‐dimethyl‐N′‐(pyridinyl‐2)‐ 6a‐6f and N,N‐dimethyl‐N‐(pyriniidinyl‐2)formamidines 6g‐6i, and (S)‐N‐trifluoroacetyl‐5‐bromo‐4‐oxonorvaline methyl ester (2) and its (R,S)‐isomer.
