A CONVENIENT DIRECT SYNTHESIS OF α-N,N-DIALKYLAMINOPHOSPHONATES UNDER APROTIC CONDITIONS
摘要:
A general one-pot synthesis of N,N-dialkylaminophosphonates under aprotic conditions is proposed using aromatic, heteroaromatic or aliphatic aldehydes and N,N-dialkyl-aminosilanes under trimethylsilyltriflate catalysis.
A CONVENIENT DIRECT SYNTHESIS OF α-N,N-DIALKYLAMINOPHOSPHONATES UNDER APROTIC CONDITIONS
摘要:
A general one-pot synthesis of N,N-dialkylaminophosphonates under aprotic conditions is proposed using aromatic, heteroaromatic or aliphatic aldehydes and N,N-dialkyl-aminosilanes under trimethylsilyltriflate catalysis.
The reductivecoupling of aromatic N,N-acetals and N,O-acetal activated by chlorotrimethylsilane proceeded smoothly in the presence of zinc to give the corresponding diamines in good yields.
