    名称:
    Investigation of a model for 1,2-asymmetric induction in reactions of .alpha.-carbalkoxy radicals: a stereochemical comparison of reactions of .alpha.-carbalkoxy radicals and ester enolates
    摘要:
    The stereochemical course of reductions and allylations of alpha-carbalkoxy radicals with chiral centers at the beta-position are reported. Radicals without polar substituents, with alkoxyl or acetoxyl groups, and with hydroxyl groups at the beta-position were examined. Reactions showed selectivities ranging from low (50:50) to high (99:1). The results are discussed in terms of transition-state models that emphasize the importance of (1) allylic conformational analysis (minimization of A1,3 and A1,2 strain), (2) torisonal strain (minimization of eclipsed interactions), and (3) stereoelectronic effects.

    摘要:
    已经开发了非常快速有效的方法,用于直接从烯烃合成邻位溴代醇和烷氧基溴化物,而无需任何催化剂。反应是在CH 3 CN-水(4:1)或酒精中,使用N,N-二溴-对甲苯甲苯磺酰胺(TsNBr 2)作为溴化剂进行的。已经获得了优异的产率以及区域选择性和立体选择性。溴代醇是瞬间形成的,而烷氧基溴化物的形成则需要30-60分钟。

    halohydrins, halo methyl ethers, and halo acetates from olefins using 2:1 Br−/BrO3− and I−/IO3− reagents. In many cases both reagents afforded products selectively in high yields. The highest halogen atom efficiencies attained were 97% and 93% for Br−/BrO3− and I−/IO3−, respectively. Of the two reagents, I−/IO3− was established to be the preferred reagent for vicinal functionalization of linear alkenes and

Numerous conventional approaches were complicated by undesired fragmentations or rearrangements.
