Abstract

The versatility and effectiveness of MnVI-NPs as a catalyst is examined for the generation of nitrile oxides from aldoximes and subsequent 1,3-dipolar cycloaddition reactions. This synthetic protocol features­ fast reaction convergence under benign reaction conditions, operational simplicity, and the use of inexpensive precursors; it avoids the use of acids or bases. The strategy offers excellent chemo-, regio-, and diastereoselectivity in the 1,3-dipolar cycloaddition reaction of in situ generated nitrile oxides with alkenes and alkynes.
