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.

the reaction with hexaethylphosphoric triamide. Their chemical transformation was selectively effected with different thionation reagents to afford thionated products at the phosphorus atom to give 3a–g and at the carbonyl group to give 4a. An oxidation reaction at phosphorus to produce 5a was effected with 10% hydrogen peroxide. Preliminary bioassays revealed that some of the title compounds, 2a–g
