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 1H and 13C NMR spectroscopy, including double resonance, DNOE and 2D HSC measurements.
