One-pot catalyst-free synthesis of benzopyrroxazine derivatives by a mutually activated sequential annulation process

Abstract

A one-pot catalyst-free reaction of o-hydroxyaryl azomethine ylides, vinyl pyridines and paraformaldehyde for the synthesis of benzopyrroxazines is reported, which offers a straightforward and atom-economical procedure for the preparation of...

Water‐assisted, Highly‐selective and Rapid Synthesis of Cyclopropane Derivatives by a [2+1] Annulation Reaction

“…Therefore further exploration of simple and effective synthetic method of cyclopropanes is still highly desirable. As part of our ongoing efforts to construct heterocycles and carbocycles, [15] herein we report a water-assisted highly-selective and rapid synthesis of cyclopropane derivatives by a [2 + 1] annulation process.…”
