Reaction of S-allyl cysteine derivatives, generated by the selenocysteine ligation, with rhodium carbenoids, stabilized and unstabilized, enables the attachment of diverse functionality onto cysteine residues. The reaction is successfully applied to the introduction of lipid-like residues, a fluorous alkyl chain, and mono- and disaccharides.
由硒代半胱氨酸连接产生的S-烯丙基半胱氨酸衍生物与稳定和不稳定的铑类胡萝卜素的反应,可使各种功能附着于半胱氨酸残基上。该反应成功地用于引入脂质样残基,氟代烷基链以及单糖和二糖。
