  摘要：

  在肽偶联条件下，使用取代的丙烯酸可一步一步完成1,3-噻嗪衍生物（1，R 1 = h）的成环反应。使用位阻丙烯酸会导致反常反应，噻嗪衍生物（1，R 1 = R 2 = Et）产生有趣的重排。

  Two templates for the preparation of external beta-turns have been synthesised. In the course of the synthetic studies an interesting dichotomy was observed in the PCl3 catalysed reaction of exocyclic enamines such as 6 and 14 with protected dehydroamino acids. When amide protected dehydroamino acids were condensed with 6 and 14 the expected 6/6 and 6/5 fused bicyclic compounds such as 7 and 15 respectively were obtained, whereas when urethane protected dehydroamino acids were used, the 5/6 and 5/5 fused products 9 and 18 were obtained.(C) 2002 Elsevier Science Ltd.
