Formation of 1,1-α,α-Glycosidic Bonds By Intramolecular Aglycone Delivery. A Convergent Synthesis of Trehalose
摘要:
[GRAPHICS]We report a new synthesis of trehalose analogs that involves the use of intramolecular aglycone delivery for stereoselective formation of the 1,1-alpha,alpha-glycosidic bond. The glycosylation reaction afforded the desired isomer exclusively and in good yield.

The first total synthesis of the branched oligosaccharide OSE‐1 of Mycobacterium gordonae (strain 990) is reported. An intramolecular aglycon delivery approach was used for constructing the desymmetrized 1,1′‐α,α‐linked trehalose moiety. A [3+2] glycosylation of the trisaccharide donor and trehalose acceptor furnished the right hand side pentasaccharide. Regioselective O3 glycosylation of L‐rhamnosyl

1a), a new triglycosidic tri-O-substituted glycolipid isolated from the Morinda citrifolia plant, and its chemical derivatives were identified to be active against major Gram-positive pathogens, particularly Streptococcuspneumoniae. Additional evidence indicated that 1a and its synthetic derivatives exerted their bactericidal activities against S. pneumoniae by selectively targeting the bacterial membrane
