Stereo- and Regio-controlled Aldol Synthesis using Relative 1,2-Asymmetric Induction

Highly stereoselective addition of nucleophiles to α-methyl-β-methylene carbonyl compounds combined with the hydromagnesiation reactions of 2-alkyl-substituted 1,3-dienes affords a practical, efficient stereo- and regio-controlled aldol synthesis.

Stereoselective Syntheses of Alkohols, XXV. - Generation of Enol Borates and Their Addition to Aldehydes

Ketone-derived enol borates, especially those having a 4,4,5,5-tetramethyl-1,3,2-dioxaborolane unit, are stable compounds,which have been prepared either by borylation of lithium enolates or by oxidation of vinylboronates.These E- or Z-enol borates add to aldehydes in a stereoconvergent reaction leading to syn-aldols.Aldehyde-derived enol borates have a high tendency towards polymerization.Their in-situ addition to aldehydes generates 4-alkoxy-1,3,2-dioxaborinanes, which are internally protected aldols.
