An efficient diastereoselective trans cyclopropanation of 3-alkylidene oxindoles with in situ generated α-diazo carbonyl compounds or α,β-unsaturated diazo compounds under metal-free conditions has been developed to synthesize 3-spirocyclopropyl-2-oxindol
Synthesis of N-substituted 3-(2-aryl-2-oxoethyl)- 3-hydroxyindolin-2-ones and their conversion to N-substituted (E)-3-(2-aryl-2-oxoethylidene)-indolin-2-ones: Synthetic sequence, spectroscopic characterization and structures of four 3-hydroxy compounds an

An operationally simple and time-efficient approach has been developed for the synthesis of racemic N-substituted 3-(2-aryl-2-oxoethyl)-3-hydroxyindolin-2- ones by a piperidine-catalysed aldol reaction between aryl methyl ketones and N-alkylisatins. These

In the presence of molecular sieve (MS) 4 A in DMF, a catalyst-free aldol condensation of a variety of aromatic and aliphatic ketones with isatins under mild reaction conditions has been developed. This approach may provide access to a wide range of 3-sub
