A range of 2-alkyl-2-cyclopenten-1-ones including the prostaglandin precursor 2-(6-methoxycarbonylhexyl)-2-cyclopenten-1-one and the jasmonoid precursor 2-[(Z)-2-pentenyl]-2-cyclopenten-1-one, have been prepared by a short synthetic route which begins with 6-methyl-5-hepten-2-one and generates the key 1,4-ketoaldehyde intermediates by a kinetic alkylation-ozonolysis procedure.
一系列2-烷基-2-环戊烯-1-酮类化合物,包括前列腺素前体2-(6-甲氧羰基己基)-2-环戊烯-1-酮和茉莉酮前体2-[(Z)-2-戊烯基]-2-环戊烯-1-酮,已通过一条简短的合成路径制备。该路径始于6-甲基-5-庚烯-2-酮,并通过动力学烷基化-臭氧化过程生成关键的1,4-酮醛中间体。
