The Ferrier rearrangement, which is widely used in carbohydrate chemistry, is generally performed under acidic conditions to give an α anomer with high stereoselectivity. We have found that 3-O-mesyl-d-glycals 2-4 were smoothly reacted with alcohols in th

Pyranoside 3,4-cis-thionocarbonates, under radical-promoted reaction conditions (method A, B, or C, described in the text), gave O-S rearrangement products, 3,4-thiolcarbonates of cis-stereochemistry, in acceptable yields. 2,3-Thionocarbonates of trans-stereochemistry also gave the rearrangement products of cis-stereochemistry preferentially in method B (photolysis with hexabutyldistannane). Although regio-control of the product was not satisfactory in most cases, some of the results suggested that the regioselectivity of the reaction is markedly influenced by the stereochemistry of the anomeric position of the substrates. The products were converted to thioglycosides (peracetate forms) by conventional means.
