J Org Chem. 2017 Dec 01;82(23):12134-12140. doi: 10.1021/acs.joc.7b01931. Epub 2017 Nov 09.

A reaction sequence comprising a formal [4 + 1] cycloaddition, an E1cb elimination, and an aromatization process is described in this work. By doing so, polysubstituted pyrroles were achieved from easily available chemicals, sulfur ylides, and α,β-unsaturated imines. This...

The generalized Phillips-Twomey method for NMR relaxation time inversion.

Journal of magnetic resonance (San Diego, Calif. : 1997)
