General description

Diastereoselectivity in [4+2] cycloaddition of 1-methoxy-2-methyl-3-(trimethylsiloxy)-1,3-pentadiene with 5-nitro-2-thiophenecarboxaldehyde was investigated.

Application

5-Nitro-2-thiophenecarboxaldehyde was used in preparation of 2, 3-dihydro-2-(5-nitro-2-thienyl) quinazolin-4-(1H)-ones and various novel oxime ether derivatives, anti-protozoan agents.

A series of new 2-(phenylthio) benzoylarylhydrazones were synthesized by acid-catalyzed condensation of hydrazide 3 with corresponding aldehydes. The chemical structures of the compounds were elucidated by FT-IR, (1)H-NMR and Mass spectra. All newly synthesized compounds were evaluated for their antimycobacterial
