摘要:
[image omitted] A simple and efficient method has been developed for the synthesis of sulfonamide phosphonates from N-tosyl aldimines and dimethyl trimethylsilyl phosphite at 0 degrees C in the presence of Amberlyst-15 as a heterogeneous catalyst.

A Rh/Ni-catalyzed cascade sequence of allylamine isomerization and hydrophosphonylation to synthesize [small alpha]-aminophosphonates has been disclosed.
Treatment of N-tosyl aldimines with dialkyl trimethylsilyl phosphites at 0 degrees C in the presence of iodine as a catalyst afforded the corresponding sulfonamide phosphonates in excellent yields within 1.5 to 2.5 h.
