- 2-Substituted 5-Nitrobenzothiophene Derivatives with Biological Activity
-
5-Nitrobenzothiophene-2-carboxaldehyde (I) reacted readily with compounds having an active methylene group in basic medium to give a variety of condensation products (IVa-g). The β-benzothiophenyl acrylic acid derivative (IVa) could also be prepared by heating the aldehyde (I) with acetic anhydride in presence of anhydrous sodium acetate. Its methyl ester (Vb) yielded upon condensation with hydroxylamine hydrochloride in alkaline medium the hydroxamic acid (VI). When (I) was reacted with acetyl glycine in presence of acetic anhydride, the azalactone derivative (IVe) was obtained, which upon heating with water was hydrolyzed to (IVf). The aldehyde (I) underwent readily Cross-Aldol condensation with acetaldehyde and/or acetone in alkaline medium to give the α,β-unsaturated carbonyl compounds (IVh) and (IVi), respectively.
