Abstract: Abstract Two novel electron accepting bis-isatins, having fused bis-lactam rings have been synthesized from corresponding pyrroloindoles 7 and 14 by one-pot direct oxidation approach involving oxidant NBS with or without co-oxidant TBHP in DMF/CHCl3. Synthesized… read more here.

Abstract: A 3-methoxythiophene-based indophenine reaction with N-(2-hexyldecyl)isatin in the presence of concentrated sulfuric acid produces an indophenine cis–trans isomeric dynamic equilibrium system, which is dominated by the (Z,E,Z) configuration with a trace of the (Z,Z,Z) configuration. read more here.
