Highly Stereoselective Synthesis of α-L-Olivomycosides via Trimethylsilyl Triflate Mediated Glycosidations of 1-O-Acetyl-4-O-isobutyryl-2,6-dideoxy-2-iodo-3-C-methyl-α-L-mannopyranose

All articles of this category A highly stereoselective synthesis of α-L-olivomycosides via trimethylsilyl triflate mediated glycosidations of 2-iodoolivomycarosyl-1α acetate 4 is described. Evidence is presented that the intermediate iodonium ion 20 is configurationally stable under the reaction conditions.
