摘要：

Perhydropyrido[1,2‐c][1,3] thiazepine adopts (CDCl3 solution, 25°C) an equilibrium containing > 98% trans‐fused conformer, in contrast to perhydropyrido[1,2‐c][1,3]oxazepine, which adopts a ca. 74% trans‐fused ⇌ 26% O‐inside‐cis‐fused conformational equilibrium. The cis‐(H‐5a, H‐8)‐8‐ethyl‐substituted derivatives of both systems show increased preference for the S/O inside cis conformations. The related 2‐tert‐butylperhydropyrido[1,2‐c][1,3]diazepine adopts predominantly the trans‐fused conformation. Copyright © 1990 John Wiley & Sons, Ltd.
