3-Cyanochromones in [3+2] cycloadditions with an azomethine ylide crossMark derived from sarcosine and formaldehyde. A short synthesis of 1-benzopyrano [2,3-c:3,4-c ‘] dipyrrolidines
Reactions of 3-cyanochromones with sarcosine and paraformaldehyde proceed diastereoselectively to give 1-benzopyrano[2,3-c]pyrrolidines and tetrahydro-1H-spiro[chromeno[2,3-c]pyrrol-9,5′-oxazolidine]-9a-carbonitriles, depending on the reactant ratio, as a result of a 1,3-dipolar cycloaddition of the intermediate nonstabilized azomethine ylide at the double bond and carbonyl group of the chromone system. The latter undergoes demethylenation and recyclization into a novel hexahydrochromeno[2,3c:3,4-c’]dipyrrole tetracyclic system on heating with hydrochloric acid. (C) 2013 Elsevier Ltd.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions. you can also check out more blogs about 99395-88-7. Application In Synthesis of (S)-4-Phenyloxazolidin-2-one.
