Reaction of substituted 1-methylthio-4,5-dihydro[1,2]dithiolo[3,4-c]-quinolin iodides with arylamines. Synthesis of novel 1,2-dithiolo[3,4-c]-quinolin-1-ylidene(aryl)amines and 10-(arylimino)-7,10-dihydro[1,2]dithiolo[3,4-c]-pyrrolo[3,2,1-ij]quinoline-4,5-diones

A series of novel (8-R-7-R'-4,4-dimethyl-4,5-dihydro-1H-[1,2]dithiolo[3,4-c]quinolin-1-ylidene)(4(2)-R"- phenyl)amines were synthesized by reaction of 4,4-dimethyl-1-methylthio-4,5-dihydro[1,2]dithiolo[3,4- c]quinolin iodides with arylamines in an efficient manner. The Stolle type reaction of the obtained compounds with oxalyl chloride gave 2-R-3-R'-10-[(4(2)-R"-phenyl)imino]-7,7-dimethyl-7,10-dihydro[1,2]dithiolo[3,4- c]pyrrolo[3,2,1-ij]quinoline-4,5-diones. The structure of the synthesized compounds were characterized by NMR spectroscopy, mass-spectrometry and elemental analyses. © 2017 Arkat USA, Inc.
