- Abstract
5,6,7,8-Tetrahydro-4 H-1,2,5-oxadiazocin-6-ones, Ring Enlargement Products from a 3-Isoxazolidinone and 3-Amino-2 H-azirines 3-Dimethylamino-2 H-azirines 1 and 4,4-dimethyl-3-isoxazolidinone ( 7) undergo already at room temperature a ring enlargement reaction to yield 5,6,7,8-tetrahydro-4 H-1,2,5-oxadiazocines of type 8. The structure of 8a has been confirmed by X-ray crystallography. The conformation of the eight-membered ring with a trans-amide group is of particular interest ( Fig. 1 and 2).
