The microwave‐assisted Kabachnik–Fields reaction of a series of 3‐amino‐6‐methyl‐2H‐pyran‐2‐ones, paraformaldehyde, and dialkyl phosphites or diphenylphosphine oxide led to α‐aminophosphonates or α‐aminophosphine oxides, respectively. The α‑aminophosphonates were obtained under solvent‐free conditions, whereas the α‑aminophosphine oxides in acetonitrile. The novel products were characterized by NMR and mass spectral data. © 2013 Wiley Periodicals, Inc. Heteroatom Chem 24:221–225, 2013; View this article online at http://wileyonlinelibrary.com.

A series of new >P(O)‐substituted succinic derivatives was synthesized by the microwave‐assisted phospha‐Michael addition of dialkyl phosphites, ethyl phenyl‐H‐phosphinate, and diphenylphosphine oxide to N‐phenyl and N‐methyl maleimide, as well as to maleic acid anhydride. © 2012 Wiley Periodicals, Inc.
