  Straightforward Synthesis of 1-Amino-2,2-dialkylcyclopropanecarboxylic Acids via Selective Saponification of 2,2-Dialkylcyclopropane-1,1-dicarboxylic Esters and Curtius Rearrangement

  摘要：

  Selective monosaponification of dimethyl 2,2-dialkylcyclopropane-1,1l-dicarboxylic esters afforded the corresponding 2,2-dialkyl-1-(methoxycarbonyl)cyclopropane-1-carboxylic acids, which were rearranged with diphenyl phosphoroazidate via a modified Curtius-type reaction to give methyl 2,2-dialkyl-1-[N-(alkoxycarbonyl)amino]cyclopropanecarboxylic esters. Selective deprotection of the carbamate or methyl cyclopropanecarboxylic ester was worked out, giving rise to a whole variety of ACC analogues. Straightforward ways to 1-amino-2,2-dialkylcyclopropanecarboxylic acids (2,2-dialkyl-ACC's) were developed.
