ABSTRACT

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 wileyonlinelibrary.com.
