The 1,3-dipolar cycloaddition of azomethine ylide generated in situ from acenaphthenequinone (isatin) and sarcosine to 7-arylmethylidene-6,7-dihydroindolizin-8(5H)-ones afforded novel 4'-aryl-1'-methyl-5'',6''-dihydro-2H,8''H- dispiro[acenaphthylene-1,2'-pyrrolidine-3',7''-indolizine]-2,8''-diones and 4'-aryl-1'-methyl-5'',6''-dihydro-8''H-dispiro[indole-3,2'-pyrrolidine-3',7''-indolizine]-2,8''(1H)-diones in moderate yields. The structures of the products were characterized thoroughly by NMR, IR, MS, elemental analysis together with X-ray crystallographic analysis.

Key words: spiroheterocycle, 1,3-dipolar cycloaddition, azomethine ylides, isatin, acenaphthenequinone
