✦ Synopsis

The coupling of acetobromosugars as glycosyl donors with partially protected or unprotected alkyl glycoside acceptors affords ortho esters such as (III) in high yields and excellent regioselectivities. They rearrange as either partially or fully protected compounds with high selectivity to 1β†’6 and 1β†’3 linked disaccharides such as (IV) by catalytic use of TmsOTf. -(WANG, W.;
