Abstract

N-Arylsulfonylation of 2-azetidinones can lead to the diastereoselective formation of oligomerization products. However, a simple increase of arylsulfonyl chloride concentration minimized oligomerization and allowed preparation of 1-arylsulfonyl-2-azetidinones in good yield.

Notes

Synthetic procedures for the preparation of the 2-azetidinones substrates will be detailed in future publications.

The arylsulfonyl chloride was added in one portion dissolved in the minimum amount of tetrahydrofuran.
