  Regio - and enantioselective bioreduction of ethyl 2,4-dioxoalkanoates and γ-Keto-α-enamino esters with fermenting baker's yeast

  摘要：

  2,4-Dioxoalkanoates 1a-d and the parent compounds gamma-keto-alpha-enamino esters 2a-d are regioselectively reduced by baker's yeast to (R)-alpha-hydroxy-gamma-ketoesters 4a-d in moderate to good chemical yield and appreciable enantioselectivity. Pig liver esterase enantioselective hydrolysis of the acetyl derivatives 3a-d, easily obtained by treatment of racemic alpha-hydroxy-gamma-keto esters 4a-d, produced the optically active (S) 4a-d in good chemical (60-92%) and optical (53-92%) yield.

  Visible light-induced synthesis of enaminones from vinyl azides and aldehydes under decatungstate photocatalysis was developed. The reaction proceeds via acyl radical generation from aldehyde, followed by its addition to vinyl azide, nitrogen elimination, hydrogen atom abstraction by the intermediate iminyl radical, and tautomerization. Photochemical synthesis was efficiently conducted under both batch
