Enantiomerically pure acetals in organic synthesis. 1. Chromatographic separability of furanoside and pyranoside acetals derived from .alpha.-hydroxy esters
摘要:
A general chromatographic separation of diastereomeric furanoside and pyranoside acetals derived from alpha-hydroxy esters is described. Application of this separation methodology is made to rapid syntheses of the diastereomers of (S)-methyl lactyl 4-deoxy-beta-erythro-pentopyranoside.
