Abstract
Multicomponent reactions involving methyl perfluoroalk-2-ynoates initiated by N-heterocycles (quinoline, isoquinoline, and benzothiazole) in the presence of isatins and diaryl 1,2-diketones allowed efficient access to trifluoromethyl-or other perfluoroalkyl-substituted spiro-1,3-oxazine derivatives. This facile transformation is regioselective and proceeded smoothly through a 1,4-dipolar intermediate under mild conditions, affording the products in good to excellent yields.
