Acyl Halide Induced Cleavage of N-Acylated Aminals
Boehme, Horst,Raude, Edgar
, p. 3421 - 3429 (2007/10/02)
Acyl halides attack N-acylated aminals 6 at the amine nitrogen as well as at the carboxamide group to form either N-halomethyl carboxamides 5 besides N,N-dialkyl carboxamides 11, or diacylamines 12 besides N,N-dialkylmethaneiminium halides 4.Depending on the variation of the substituents on both heteroatoms the cleavage may be directed to follow only one or the other pathway.Of highly synthetic interest is the broadly applicable preparation of methaneiminium salts 4 having bulky substituents on nitrogen by means of cleavage of the corresponding N,N-dialkyl-N'-formyl-N'-methylmethanediamines 6.
