Stereocontrolled synthesis of low-molecular-weight ?-O-glycosides from products of decyclization of acylated oligosaccharide glycals
摘要:
Low-molecular-weight beta-O-glycosides with aliphatic polyfunctional aglycones were synthesized by Horner-Emmons olefination of O-glycosylated alpha,beta-unsaturated aldehydes prepared by acid opening of the dihydropyran ring in totally acylated lactal, cellobial, and gentiobial.
