4-Phosphoranylidene-5(4H)-oxazolones ? A novel synthesis and properties
摘要:
4-Phosphoranylidene-5(4H)-oxazolones (2), a hardly known class of phosphorus ylides, were readily prepared from 4-unsubstituted-5-(4H)-oxazolones (1) by treatment with Ph(3)P-Br-2, Bu(3)P-Br-2, Ph(3)P-CCl4, or Ph(3)P-CB4 adducts in the presence of triethylamine in CH2Cl2 at room temperature in a novel, efficient one-pot procedure. The spectroscopic properties of the ylides are reported and discussed.

A new Pd(II)-catalyzed cascade sequence for the formation of polyheterocycles, from simple starting materials, is reported. The sequence is applicable to both indole and pyrrole substrates, and a range of substituents are tolerated. The reaction is thought to proceed by a Pd(II)-catalyzed C–H activated Heck reaction followed by a second Pd(II)-catalyzed aza-Wacker reaction with two Cu(II)-mediated
