Novel isocyanide-based one-pot multicomponent syntheses of tetrahydrobenzo[b][1,4]oxazepine and malonamide derivatives.

In this work, a novel one-pot multicomponent reaction of 2-aminophenols, Meldrum's acid, and isocyanides leads to the synthesis of tetrahydrobenzo[b][1,4]oxazepine or malonamide derivatives using 1 or 2 equiv of 2-aminophenols, respectively, in good to excellent yields at ambient temperature.
