The total synthesis of lactonamycin has been achieved. The synthesis includes sequential intramolecular conjugate addition of alcohols to the acetylenic ester, stereoselective glycosylation of the tertiary alcohol, and Michael-Dieckmann type cyclization w
PREPARATION AND CYCLOADDITION OF FUNCTIONALIZED 4,6-DIALKYLPYRONE-5-CARBOXYLATES. SYNTHESIS OF BICYCLIC LACTONES AND SUBSTITUTED BENZOATES

, p. 117 - 121 (2007/10/02)
Several alkyl pyrone-5-carboxylates (coumalates) with alkyl and functionalized alkyl substituents at C4 and C6 have been prepared by a general route; their cycloadditions with electron-rich olefins have been carried out to provide aromatic and non-aromati
THERMAL ADDITION REACTIONS TO BENZOCYCLOBUTENONES STUDIED BY FLASH PHOTOLYSIS

Ortho-quinoid vinylketenes 2 have been generated thruogh flash photolysis of benzocyclobutenones 1.A kinetic study of intermolecular addition reactions of 2 competing with the recyclization 2 -> 1 reveals strikingly different substituent effects for the addition of methanol and of dienophiles.
