[HP(HNCH2CH2)3N]NO3: an efficient homogeneous and solid-supported promoter for aza and thia-Michael reactions and for Strecker reactions

Compound A is an efficient homogeneous catalyst for the generally room temperature synthesis of Strecker products and Reissert compounds in three and four-component one-pot transformations, respectively, and also for aza and thia-Michael addition products. Polymer supported B is an equally efficient catalyst for these reactions, showing impressive recycling/regeneration capabilities.
