Noteworthy observations accompanying synthesis of the apoptolidin disaccharide

A stereoselective synthesis of the apoptolidin disaccharide is reported. The key chemistry features a new transformation utilizing a highly selective tetramethylalkoxyalanate[v]-directed syn-methylation of a vinylogous ester, isolation of a hydrate of a 2-keto sugar, an eco-friendly radical cleavage of a bromomethyl group, and an efficient preparation of a fluorodisaccharide via the use of XtalFluor-E.

Improvements in the regioselectivity of alkylation reactions of stannylene acetals

The regioselectivity of benzylation of stannylene acetals of trans-diols on pyranose rings is improved by performing the reaction in benzyl bromide, for instance, for methyl 4,6-O-benzylidene-2,3-O-dibutylstannylene-α-D-glucopyranoside, the ratio of 2-O-b
