Lithium trialkylalkynylborates (1) react with oxiranes (2) to give non-isolable intermediates 3 which subsequently afford either γ-hydroxyketones 5, trisubstituted ethylenes of homoallylic alcohol type 6 or a tetrasubstituted ethylene 7 upon appropriate treatment with NaOH/H2O2, AcOH or NaOH/I2, respectively. The reaction of oxiranes with 1 proceeds in high regioselectivity and the resulting homoallylic
三烷基炔基硼酸锂(1)与环氧乙烷(2)反应生成不可分离的中间体3,随后经NaOH / H 2 O 2适当处理,可得到γ-羟基酮5,均烯丙基醇类型6的三取代乙烯或四取代乙烯7,分别为AcOH或NaOH / I 2。环氧乙烷与1的反应以高区域选择性进行,并且所得到的均烯丙基醇6具有接近100%(E)构型。直链γ-羟基酮16在甲氧基环氧乙烷与由乙炔化乙二胺锂络合物和三己基硼烷制得的酯络合物(1)的反应中获得了β-环糊精。

Oxidative cleavage of cyclobutanols using PIDA, which leads to efficient entry of gamma-hydroxy ketones, is described. When using 2-substituted cyclobutanols, gamma-substituted gamma-hydroxy ketones are obtained through regioselective C-C bond cleavage. (C) 2010 Elsevier Ltd. All rights reserved.
