1,3-Dipolar Cycloaddition Reaction of Dibenzalaceton with Non-stabilized Azomethinylides: Synthesis of New Spirooxindolo(pyrrolizidines/ pyrrolidines)

1,3-dipolar cycloaddition reaction of 1 mol or 2 mol of dibenzalaceton with 1 mol of non-stabilized azomethinylides generated in situ by decarboxylative condensation of isatin and proline or sarcosine give the novel new spiro-oxindolo(pyrrolizidines/ pyrrolidines) instead of bis-spirooxindolo( pyrrolizidines/ pyrrolidines).

PREPARATION OF (CHLOROCARBONYL) PHENYLKETENB AND ITS CYCLOADDITION REACTION WITH BENZALDEHYDEV

Meldrum's acid, 2'5-diphenyl-1'3-dioxane-4'6-dione, was produced by [2+2] cycloadditions of the (chlorocarbony1)phenylketene with benzaldehyde. Acid hydrolysis of the meldrum's acid regenerated benzaldehyde and also yielded phenylacetic acid as the final product
