Abstract: [3 + 2]-Cycloaddition of azomethine ylide generated from formaldehyde and sarcosine at the double bond of 1,3-dimethyl-6-(2-oxo-1,2-dihydro-3H-indol-3-ylidene)-3a,9a-diphenyl-3,3a,9,9a-tetrahydroimidazo[4,5e][1,3]thiazolo[3,2-b][1,2,4]triazine-2,7(1H,6H)-diones occurs stereospecifically at the face opposite to the phenyl substituents. Product 3a crystallizes as a conglomerate.
