Page/Page column 19, (2010/11/28)
The invention relates to a process for the preparation of meropenem, a β-methylcarbopenem. The said process comprises the following steps: preparing the compound of Formula (XI) from the compound of Formula (IV) through three steps "one-pot process"; then condensing the compound of Formula (XI) with the compound of Formula (XX) to form the compound of Formula (XXIV); finally preparing meropenam of Formula (I) from the compound of Formula (XXIV) by deprotection reaction by means of catalyst. The process of the invention is easily to carry out, the product is isolated in high content and yield, and the cost is reduced, thereby overcoming the shortage of the prior art.
