Despite recent advances in the use of alkyl azides in ring expansion reactions of ketones, there has been little work done on the corresponding chemistry of aldehydes. In the present study, the Lewis acid-promoted reactions of alkyl azides with aldehydes

A convenient preparative route has been developed for the synthesis of hexahydropyrroloisoquinolines involving condensation of an araldehyde with ethyl 4-nitrobutanoate followed by LAH reduction and subsequent cyclization with H2SO4 to 2-arylmethylpyrrolidines.The latter on formylation and Bischler-Napieralsky cyclization followed by NaBH4 reduction give the required pyrroloisoquinolines.Using this method, 8-methoxy-1,2,3,5,10,10a-hexahydropyrroloisoquinoline (IXa); 7,8-dimethoxy-1,2,3,5,10,10a-hexahydropyrroloisoquinoline (IXb); 7,9,10,11,11a,12-hexahydrobenzopyrroloisoquinoline (Xa); 3-methoxy-7,9,10,11,11a,12-hexahydrobenzopyrroloisoquinoline (Xb); 7,7a,8,9,10,12-hexahydrobenzopyrroloisoquinoline (XIa); 3-methoxy-7,7a,8,9,10,12-hexahydrobenzopyrroloisoquinoline (XIb) and 2,3-dimethoxy-7,7a,8,9,10,12-hexahydrobenzopyrroloisoquinoline (XIc) have been synthesized.None of these compounds has shown any noteworthy anticancer activity while few have exhibited interesting antihistaminic, β-blocking, hypertensive, antiinflammatory and antireserpine activities.
