  一种由芳基α-卤代烷基亚砜与烷基金属生成α-卤代碳负离子（类固醇）的方法

  摘要：

  研究了简单的芳基α-卤代烷基亚砜与烷基锂和乙基镁卤化物在低温下的配体交换反应。在用n-BuLi，t-BuLi或EtMgX处理芳基α-卤代烷基亚砜时，只有硫-烷基键断裂才可得到α-卤代碳负离子（类胡萝卜素）。当该反应在没有质子源的情况下进行时，中间体α-卤代碳负离子分解以高收率得到烯烃。发现亚砜的配体交换反应非常快，该反应可以用质子或氘源（内部淬灭）进行，得到烷基卤。该程序提供了一种制备α-氘代卤化物（卤素为F，Cl或Br）的新方法。

  Iterative Stereospecific Reagent-Controlled Homologation of Pinacol Boronates by Enantioenriched α-Chloroalkyllithium Reagents

  摘要：

  Reaction of pinacol boronates with putative enantioenriched alpha-chloroalkyllithium species, generated in situ from homochiral alpha-chloroalkylsulfoxides by sulfoxide ligand exchange with t-BuLi in PhMe at -78 degrees C, gave chain-extended boronic ester products with generally excellent stereochemical fidelity. Iteration of this stereospecific reagent-controlled homologation (StReCH) process enabled the programmed synthesis of all four stereoisomers of a stereodiad-containing model system (4-benzyl-1,6-diphenylhexan-2-ol) with er >= 97:3 in all cases.

The magnesium enolates derived from the α-chloro-α-sulfinyl acid derivatives were trapped with carbonyl compounds to afford the adducts, which were transformed to α, β-epoxy carboxylic acid derivatives. Thermal elimination of the sulfinyl group in the α-halo-α-sulfinyl acid derivatives and the α-halo-α-sulfinyl aldehydes gave α-halo-α, β-unsaturated carboxylic acid derivatives and α-halo-α,

  Addition of the carbanion of 1-chloroalkyl p-tolyl sulfoxide to carbonyl compounds gave the adducts, which were heated in refluxing toluene or xylene to give vinyl chlorides in high overall yield. Dehydrochlorination of the vinyl chlorides with excess n-BuLi afforded propargylic alcohols in high yields. Asymmetric synthesis of both enantiomers of the propargylic alcohols was realized using optically

  Ligand exchange reaction of simple aryl α-haloalkyl sulfoxides with alkyllithium and ethylmagnesium halide at low temperature was investigated. On treatment of aryl α-haloalkyl sulfoxide with n-BuLi, t-BuLi, or EtMgX exclusively sulfur-alkyl bond-cleavage took prace to afford α-halo carbanion (carbenoid). When this reaction was carried out without a proton source, the intermediate α-halo carbanion
