Abstract

Two nonproteinogenic amino acids 5 and 6 have been efficiently prepared using an SH2′ allylstannane coupling reaction and a Wittig reaction, respectively, to effect the key steps; kinetic studies show these compounds to be reversible inhibitors of DAP dehydrogenase with Ki values of 5.3 (competitive) and 44 µM (noncompetitive), respectively.
