Two syntheses of some optically active 2-benzyl-2,3-dihydro-4H-benzopyrans and benzopyran-4-ones are presented. An asymmetric synthesis starting from D- and L-phenylalanine was used to provide both enantiomers of 2-benzyl-6-(methoxycarbonyl)-2,3-dihy

In studying the synthesis of tigogenyl β-O-cellobioside 1 via the trichloroacetimidate method of Schmidt, cesium carbonate was found to be an efficient reagent for the synthesis of peracetylated disacchadde α-trichloroacetimidates. Zinc bromide was
