straightforward synthetic route of lβ-methylcarbapenem precursor is established by hydrogenolysis-isomerization-reduction process of propargyl acetate or by regio- and stereoselective hydrogenation process of dienyl ester with complete stereoselectivity.
通过乙酸炔丙酯的氢解-异构化-还原过程或具有完全立体选择性的二烯酯的区域和立体选择性加氢过程,建立了1β-甲基碳青霉烯前体的直接合成路线。
