methyl hydrogen (R)-3-methylglutarate(2) is a useful chiral building block for the synthesis of several biologically active compounds. Enantiomerically pure (R)-2 has been employed to synthesize stereospecifically each of the two enantiomers, 1a and 1b, of 10-methyl-2-tridecanone, the sex pheromone of the southern corn rootworm, Diabrotica undecimpunctata howardi Barber. Compound (R)-2 has been also
现成的甲基氢(R)-3-甲基戊二酸甲酯(2)是用于合成几种生物活性化合物的有用的手性结构单元。对映体纯的(R)-2已被用于立体定向合成10-甲基-2- tretcanone的两个对映体1a和1b,这是南部玉米根虫性信息素Diabrotica undecimpunctata howardi Barber的性信息素。化合物(R)-2也已用于制备99%光学纯度(R)-3-甲基-1-戊醇(6)和对映体纯度(R)-5-甲基-异三甲苯胺(7)。这些化合物是适用于进一步修饰成其他手性昆虫信息素的有用的结构单元。
