α-Phosphoramidolithium substituted allylic carbanions are used as homoenolate reagents with benzophenone and give regioselectively α- or γ-hydroxyalkylation products. Replacement of lithium by magnesium leads to γ substitution almost exclusively. Acidic hydrolysis of the adducts is a novel route to γ-lactol.

1,1-Disubstituted alkenes feature high steric hindrance, which renders their Wacker-type oxidation difficult. We demonstrate the stereoselective synthesis of 2-hydroxytetrahydrofurans via the Wacker-type oxidation of 3-methyl-3-buten-1-ols by using a PdCl2(MeCN)2/NO/BQ catalyst system under 1 atm O2 in H2O or H2O/DMF.
1,1-二取代烯烃具有高位阻,这使得它们的瓦克型氧化变得困难。我们通过使用 PdCl 2 (MeCN) 2 /NO/BQ 催化剂体系在 H 2中的 1 atm O 2下通过Wacker 型氧化 3-methyl-3-buten-1-ols展示了 2-羟基四氢呋喃的立体选择性合成。O或H 2 O/DMF。
