SYNTHETIC STUDIES OF CARBOHYDRATE DERIVATIVES WITH PHOTOCHEMICAL REACTION. IV. PHOTOCHEMICAL ADDITION REACTION OF SECONDARY ALCOHOLS TO METHYL 4,6-DI-O-ACETYL-2,3-DIDEOXY-α-D-erythro-HEX-2-ENOPYRANOSIDE
Photochemical addition reaction of 2-propanol to methyl 4,6-di-O-acetyl-2,3-dideoxy-α-D-erythro-hex-2-enopyranoside was found to give methyl 4,6-di-O-acetyl-2,3-dideoxy-2-C-(1-hydroxy-1-methylethyl)-α-D-erythro-D-glycero-hexopyranoside in 66% yield. A series of secondary alcohols were also found to give such addition products in the photochemical reaction.
