The addition reaction of diketene in formic, acetic or propionic acid to isoquinoline afforded 1-acetonyl-2-acyl-1,2-dihydroisoquinoline (II) in satisfactory yields.Though no reaction of this type was observed to occur in quinoline, isoquinoline-like N-heteroaromatic compounds such as phthalazine and 1,6-naphthyridine underwent similar addition reactions to give the corresponding dihydro-acetonyl compounds.The above product II was easily convertible to benzoquinolizine derivatives.Keywords - diketene; mixed anhydride; isoquinoline; phthalazine; 1,6-naphthyridine; 1,2-dihydroisoquinoline
