Abstract

2 + 2‐Cycloaddition reactions of cis‐ and trans‐cyclopenta‐, ‐cyclohexa‐ and ‐cyclohepta‐ and trans‐cycloocta [e]‐2‐phenyl‐4H‐1,3‐thiazines gave new types of hydrated tricyclic 1,3‐thiazino‐β‐lactam derivatives having the 2‐phenyl substituent and H‐9 in cis positions. The configurations and conformations of the new compounds were determined by ^1^H and ^13^C NMR spectroscopy, including double resonance, DNOE and 2D HSC measurements.
