摘要
We document an efficient and cost-effective synthesis of ramipril 1 utilizing (i) an environmentally benign process for the esterification of racemic 2-aza-bicyclo-[3.3.0]-octane-3-carboxylic acid hydrochloride 2 using boric acid as a catalyst and (ii) a robust resolution process for the synthesis of 3a by means of inexpensive and recyclable L-(+)-mandelic acid as key steps.
