A NEW SYNTHETIC APPROACH TON,N′-DISUBSTITUTED 1,n-ALKANEDIAMINES
摘要:
A general procedure is described for the synthesis of unsymmetrically substituted N-aryl-N'-alkyl (or aryl) 1,n-alkanediamines 1 (n = 2-5) by reduction of omega -alkyl (or aryl) aminoalkanamides 2 with borane. Compounds 2 are easily obtained by aminolysis of the corresponding omega -haloalkanamides 3.

3-propanediamines (5) with trimethylsilyl polyphosphate (PPSE). Quaternization of compounds (1) with methyl (or ethyl) iodide led to the corresponding cyclic amidinium salts (2), while treatment of compound (1a) with 2,4-dinitrochlorobenzene yielded an open chain product resulting from hydrolysis of the salt. An alternative method was employed for the synthesis of 1-aryl-1,4,5,6-tetrahydropyrimidinium salts bearing
