| Abstract: | Nonstabilized azomethine ylides react with 4-arylidene-2-phenyloxazol-5(4H)-ones to form diazaspiro[4.4]nonenes, which were hydrolyzed to aryl cucurbitine derivatives in 35–67% overall yield. |
| Keywords: | Nonstabilized azomethine ylides Pyrrolidines Cucurbitine Azaheterocycles [3+2]-Cycloaddition |
