Two templates for the preparation of external β-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 dehyd

One-step annelation of the 1,3-thiazine derivatives (1, R1 = H) is achieved using substituted acrylic acids under peptide coupling conditions; use of sterically hindered acrylic acids results in an anomalous reaction and the thiazine derivative (1, R1 = R
