  Utility of tetrathiomolybdate and tetraselenotungstate: efficient synthesis of cystine, selenocystine, and their higher homologues

  摘要：

  Efficient synthesis of cystine, selenocystine, and their higher homologues like homo and bishomo amino acid derivatives from natural amino acid derivatives using tetrathiomolybdate and tetraselenotungstate reagents under mild and neutral conditions is reported. The generality of the reaction has been studied by capping various groups to amino and carboxyl components of canonical amino acids. (C) 2003 Elsevier Science Ltd. All rights reserved.

  Radical addition of H3PO2 to N-/C-protected vinyl glycine led to the corresponding H-phosphinic acid in excellent yield. The non-nucleophilic H-phosphinic acid was converted to a nucleophilic PIII species, RP(OTMS)2, which was used in two approaches to the target phosphinic acid containing pseudopeptide. New methodology was developed that led to excellent yields in the reaction of RP(OTMS)2 with unactivated

  Optically pure (L)-vinylglycine has been synthesised by two different methods. The first of these involves protected (L)-glutamate esters of N-hydroxy-2-seleno-pyridine. Such esters are shown to undergo the same decarboxylotive rearrangement as their thio-analogues. Oxidative elimination of the selenopyridine residue with ozone, and with the aid of hex-1-ene as sacrificial olefin for the work-up, gave

  光学纯的（L）-乙烯基甘氨酸已经通过两种不同的方法合成。这些中的第一个涉及N-羟基-2-硒代吡啶的受保护的（L）-谷氨酸酯。这类酯显示出与其硫代类似物相同的脱羧基重排。用臭氧氧化除去硒吡啶吡啶残基，并借助于己烯-1-烯作为后处理的牺牲烯烃，得到所需的（L）-乙烯基甘氨酸衍生物。类似地，在适当保护的（L）-谷氨酸衍生物的末端羧基上的修饰的Hunsdiecker反应产生了正溴化物，其在用苯基硒化物阴离子处理时容易得到相应的苯基硒化物。顺序则如上所述。
