Pd. Cunningham et al., THE REACTION OF CYCLIC 2-DIAZO-1,3-DICARBONYL COMPOUNDS WITH BETA-LACTONE AND GAMMA-LACTONE - FORMATION OF BENZODIOXEPINONES, BENZODIOXECINONES AND BENZOFURANS, Journal of the Chemical Society. Perkin transactions. I, (1), 1997, pp. 1-4
A novel reaction of cyclic 2-diazo-1,1-dicarbonyl compounds with lacto
nes is described which, depending on the structure of the lactone, aff
ords benzodioxepinones, benzodioxecinones or benzofurans.
