F. Casuscelli et al., RING-OPENING OF CARBOXY-SUBSTITUTED ISOXAZOLIDINES - SYNTHESIS OF LACTONES AND ALPHA-HYDROXY-GAMMA-LACTAMS, Gazzetta chimica italiana, 127(7), 1997, pp. 367-371
The synthetic possibilities offered by isoxazolidines containing a car
boxy group at various position of the N,O-ring have been exploited. A
new easy entry towards substituted delta-lactones is described.
