A NOVEL METHOD FOR THE SYNTHESIS OF α,β-DIHYDROXY KETONES via TIN(II) ENEDIOLATES

Mukaiyama, Teruaki,Kato, Jun-ichi,Yamaguchi, Masahiko

, p. 1291 - 1294 (1982)

Activated metallic tin, prepared from stannous chloride and metallic potassium, reacts readily with α-dicarbonyl compounds to form tin(II) enediolates, which in turn react with aldehydes under a mild reaction condition to give α,β-dihydroxy ketones in good yields.The reaction proceeds stereoselectively in the presence of hexafluorobenzene.
