SYNTHETIC STUDIES OF CARBOHYDRATE DERIVATIVES WITH PHOTOCHEMICAL REACTION. VII. PHOTOCHEMICAL ADDITION OF ETHANETHIOL AND 1-PROPANETHIOL TO ENOSES

Abstract
Acetone-sensitized photochemical addition of ethanethiol and 1-propanethiol to 2,3,4,6-tetra-O-acetyl-2-hydroxy-d-glucal gave the corresponding α-thioglucopyranosides in 77.1% and 79.3% yields, respectively. Similar addition reactions of thiols to methyl 4,6-di-O-acetyl-2,3-dideoxy-α-d-erythro-hex-2-enopyranoside and 3,4, 6-tri-O-acetyl-d-glucal were also described.
