摘要

Seven-membered ring fused sydnones,4,6-diaryl-4,6,7,8-tetrahydro-[1,4]oxazepino[4,3-c]sydnones (2) were prepared-via oxa-Pictet-Spengler reaction of 3-(3-phenyl-3-hydroxypropyl)sydnone (1) with aromatic aldehydes in the presence of Lewis acid.The reactions gave two stereoisomers ( cis- and trans-),and the cis- isomers were the major products.
