Bromodimethylsulfonium bromide catalyzed synthesis of methyl 2-dexoy-4,6-o-benzylidene galactopyranoside from galactal and the rapid route to 2,3- and 2,6-dideoxygalactopyranoses

4,6-O-Benzylidenation of D-galactal with PhCH(OCH3)2 catalyzed by bromodimethylsulfonium bromide leads to methyl 2-dexoy-4,6-O- benzylidene galactopyranoside efficiently, which serves as a key intermediate to the ready preparation of

Site-selective catalysis of phenyl thionoformate transfer as a tool for regioselective deoxygenation of polyols

(Chemical Equation Presented) We report the application of peptide-embedded imidazoles as catalysts for the site-selective delivery of the phenyl thionoformate unit as a prelude to deoxygenation reactions of polyols. Methodology was developed that allows for the synthesis of thiocarbonyl derivatives based on a combination of additives that include N-alkylimidazoles and FeCl3 as co-catalysts. The use of this reagent combination leads to increased reaction rates and efficient yields relative to those of simple base-mediated reactions. In terms of controlling regioselectivity during the course of polyol modification, we found that histidine-containing peptides, in combination with FeCl3, could lead to modulation of the product distribution. Through screening of peptides and control of reaction conditions, products could be observed that reflected both the inherent preference of substrates and also reversal of inherent selectivity.

Process for deoxygenating secondary alcohols

The process for removing a secondary hydroxyl group from an organic compound having at least one secondary hydroxyl group and having any amino groups protected, comprises the reaction of a reactive ester of said secondary hydroxyl group selected from the group consisting of an O-alkylthioester and an O-alkylselenoester with at least one mole of an organotin hydride, preferably tri-n-butylstannane, in an inert, aprotic solvent at a temperature of at least about 100° C and under an inert atmosphere. The process is particularly useful in removing secondary alcohols in aminoglycoside antibiotics to produce deoxy derivatives thereof having antibacterial activity. Also described are novel O-sec.-alkylthiobenzoate, O-sec.-alkyl-S-methylxanthate, N-(sec.-alkoxythiocarbonyl)-imidazole esters, and di-O-alkylthiocarbonates having at least one secondary O-alkyl group, useful intermediates of the claimed process.
