资源简介:
The highly diastereoselective oxy-Michael addition of the “naked” anion of (6S)-methyl δ lactol to alkylidiene-, arylidene-, and heteroarylidenemalonate derivatives leading to the direct formation of THP*-protected β-hydroxy ester derivatives is described. Subsequent acid-mediated deprotection affords the enantioenriched aldol products in quantitative yields.
