A divergent strategy for constructing a sugar library containing 2,6-dideoxy sugars and uncommon sugars with 4-substitution

A practical strategy has been developed for delivering 2,6-dideoxy sugars and uncommon sugars with 4-substitution. This strategy employed Ferrier rearrangement reaction and BF3·OEt2-induced peroxidation to construct key intermediates 2,3-unsaturated glycosides and α,β-unsaturated lactones from peracetyl rhamnal. After further derivatization, four uncommon sugars with 4-substitution and eight uncommon sugar units with 3,4-disubstitution were successfully synthesized.

A systematic strategy for preparation of uncommon sugars through enzymatic resolution and ring-closing metathesis

A systematic synthetic strategy has been developed for producing uncommon sugars. This method involved kinetic resolution allylic alcohol followed by ring-closing-metathesis (RCM) to generate optical pure lactones as the common precursors. After further d

Synthesis of 2,6-dideoxysugars via ring-closing olefinic metathesis.

[formula: see text] Grubbs' RuCl2 (=CHPh)(PCy3)2 (catalyst 1) and RuCl2(=CHPh)(PCy3)(IMess) (catalyst 2) complexes have been successfully utilized in the construction of beta,gamma-unsaturated delta-lactones containing various substitution patterns of methyl groups. Asymmetric dihydroxylation followed by reduction leads to 3,4-cis-dihydroxy-2,6-dideoxypyranoses, which have proven to play very important biological roles as key components of natural products.
