aniline resulted Schiff’s bases 4. The compounds 4 was further reacted with various aldehydes having α-hydrogen using molecular iodine as a catalyst and obtained 2-alkyl triazole-3-alkyl substitutedquinolinederivatives 5. All the final compounds were screened against four human cancer cell lines (THP-1, Colo205, U937 & HeLa) and promising compounds have been identified.
novel 1,2,3-triazole substituted N-phenyl nitrone derivatives 5a–e were prepared in three steps starting from 1-substituted-1,2,3-triazole-4-carbaldehydes 2 via Schiff's base formation, reduction followed by oxidation. Similarly, 1,2,3-triazole substituted N-alkylnitrone derivatives 6a–p were prepared in single step starting from compound 2 on reaction with N-alkyl hydroxylamine hydrochlorides. All the
