摘要: The present invention provides a process for preparing a penicillanic acid derivative of the formula
which comprises reacting lead with a halogenated penicillanic acid derivative of the formula
wherein X, Y, Z and R¹ are defined in the specification. The reaction is conducted more advantageously in the presence of a metal having higher ionization tendency than lead.摘要翻译: 本发明提供了一种制备式CHEM的青霉烷酸衍生物的方法,其包括使引线与式CHEM的卤代青霉烷酸衍生物反应,其中X,Y,Z和R 1在本说明书中定义 。 在具有比铅更高的电离倾向的金属的存在下,更有利地进行反应。
