Facile P,N-heterocycle synthesis via tandem aminomethylation-cyclization of H-phosphinate building blocks
Queffelec, Clemence,Montchamp, Jean-Luc
, p. 267 - 273 (2010)
Various heterocycles containing phosphorus and nitrogen are easily synthesized from readily available H-phosphinate building blocks. Aminomethylation of these H-phosphinates is followed by in situ cyclization through substitution or cross-coupling to prod
