Divergent synthesis provides an indispensable route to rapid acquisition of structurally diverse chemical scaffolds from identical starting materials. Herein, we describe unprecedented divergent annulations of o-hydroxyarylenaminones promoted by tert-butyl nitrite (TBN) under mild conditions. Two different types of benzo-oxa-heterocycle, including oximinochromanones and oximinocoumaranones, were smoothly assembled with a broad substrate scope and good functional group compatibility.

A sequential one-pot, simple and convenient method is described for the synthesis of 3-selenocyanato-4 H -chromen-4-ones by addition, first of DMF-DMA and then of triselenodicyanide as electrophile.
