Syntheses in the Series of Pyrazolyl-substituted Quinoxalines
摘要:
Starting from 3-(3-chloro-1H-pyrazol-5-yl)-1H-quinoxalin-2-one (2), a dihydroquinoxalinone derivative (6) was synthesised as potential HIV-1 reverse transcriptase inhibitor. Moreover, a series of N(4)-[3-(3-pyrazolyl)-2-quinoxalinyl]-N(1),N(1)-diethyl-1,4-pentanediamines (compounds of type B) and N-[3-(3-pyrazolyl)-2-quinoxalinyl]-N-(3-pyridyl)methylamines (11-13)- structurally related to antimalarial agents - could be prepared via the 2-chloro-3-[3(5)-chloro-1H-pyrazol-5(3)-yl]quinoxaline (7). The position of the alkyl substituent on the pyrazole nitrogen was determined unequivocally from NOE difference experiments or X-Ray structure analysis.
