    Lipase-catalyzed kinetic resolution of Z-configured homoallylic alcohols
    摘要:
    Racemic Z homoallylic alcohols were prepared by the BuSnCl3-catalyzed addition of aldehydes to 1-(tributylstannyl)-2-butene. These alcohols were resolved for the first time by lipase-catalyzed enantioselective acetylation in up to 98% enantiomeric purity. (C) 1999 Elsevier Science Ltd. All rights reserved.

  • Zur “cis-präferenz” bei der addition von butenyl-metallverbindung an ketone und aldehyde
    作者:Reinhard W. Hoffman、Ulrich Weidmann
    DOI:10.1016/s0022-328x(00)89998-2
    日期:1980.8
    Esters of 1-butenyl-3-boronic acid add to aldehydes forming 2-butenyl-1-carbinols, the E/Z-ratio of which varies between 31 and 12 depending on the steric requirements of the ester component. The steric bulk of the groups coordinating the metal ion is discussed as a potential cause of the “cis-preference” observed on addition of butenylmetal derivatives to ketones.

    日期:2012.5
    α-regioselectivity of carbonyl crotylation is a long-standing problem in the realm of C–C bond formation reactions. We demonstrate that zinc-mediated crotylation of aldehydes and ketones can afford α-linear homoallylic alcohols exclusively to provide a simple solution for this problem. In this context, we describe a method for the α-regioselective crotylation of aldehydes and ketones by using an easily available
    羰基巴豆化的 α-区域选择性是 C-C 键形成反应领域的一个长期存在的问题。我们证明了介导的醛和酮的巴豆化可以专门提供 α-线性高烯丙醇,从而为该问题提供简单的解决方案。在这方面,我们描述了一种使用容易获得的起始材料(例如巴豆粉和毒性较小的溶剂 DMPU)对醛和酮进行 α-区域选择性巴豆化的方法。该反应底物范围广,效率高。此外,提出了属-[3,5]-σ 重排以解释介导的巴豆化中的高α-区域选择性。

    Reactions between allylstannanes, R2CH=CHCHR1SnBu3 (R1 = R2 = H (4); R1 = H, R2 = Me (5); R1R2 = (CH2)3 (6)) and aldehydes, RCHO (e.g. R = Et) in the presence of BF3 · OEt2 in CH2Cl2 at −78°C produce stereoselectively erythro-RCH(OH)CHR2CH=CHR1 (with one equivalent RCHO) and 4-OH-3-R1-5-R2-2,6-R2-tetrahydropyrans (with an excess of RCHO). In contrast, when BCl3 is used in place of BF3 · OEt2 the reactions
