A series of novel N-methyl spiropyrrolidines have been synthesized in good yield by the cycloaddition reaction of azomethine ylides generated by a decarboxylative route from sarcosine and paraformaldehyde with conformationally locked s-trans enone functionality present in the (E)-3-arylidene-4-chromanone as dipolarophiles. The structure of the title compound was established by spectroscopic techniques. Copyright Taylor & Francis, Inc.
