An efficient method to selectively construct benzofuran and dihydrobenzofuro[2,3-d]oxazole derivatives has been successfully established by means of base-controlled cyclization of N-phenoxyamides with 1-[(triisopropylsilyl)ethynyl]-1,2-benziodoxol-3(1H)-one (TIPS-EBX). N-phenoxyamides as multitasking reagents have triggered two different cascade reaction sequences. This is the first example of using TIPS-EBX for the transformation of C(sp) to either C(sp2) or C(sp3) under metal-free conditions.

A rhodium(III)-catalyzed electrophilic amination of arylboronic acids with secondary hydroxylamines has been developed. The rhodium catalysis is compatible with heteroarylboronic acids as well as acyl and alkoxycarbonyl protecting groups on the nitrogen of O-acylhydroxylamines, and the corresponding secondary anilines are obtained in good to excellent yields.

The synthesis of novel 3-aryl-2-arylamidobenzofurans has been accomplished via a Curtius rearrangement strategy in four steps from benzofuran-2-carboxylic acids. The requisite Suzuki-Miyaura cross-coupling, with benzyl 3-bromobenzofuran-2-ylcarbamate or 2
