A new asymmetric total synthesis of enantiopure (−)-methyl jasmonate is described. This synthesis was accomplished starting from the new enantiopure building block prepared via the catalytic asymmetric intramolecular cyclopropanation (IMCP) of the α-diazo-β-keto 1-naphthyl sulfone, which was devised to give good selectivity both in the IMCP reaction and in the C-alkynylation of the intermediate required
描述了一种新的不对称全合成的对映纯(-)-茉莉酸甲酯。该合成是从新的对映纯结构单元开始的,该新对映体结构单元是通过α-重氮-β-酮基1-萘砜的催化不对称分子内环丙烷化(IMCP)制备的,该结构被设计为在IMCP反应和反应中均具有良好的选择性。对映纯(-)-茉莉酮酸甲酯的全合成所需的中间体的C-炔基化。
