STEREOCONTROLLED FORMATION OF 1,2-DIHYDROINDOLES

Imines 4 cyclize stereoselectively to dihydroindoles 2 upon use of a Li or Na alkoxide-alcohol combination.Depending on the type of alcohol applied either cis (2C) or trans (2T) spiroindolines 2 are formed.In case of imines 4 derived from electron-rich ar

STEREO- AND ENANTIOSELECTIVE SYNTHESES OF 2,3-DIHYDROINDOLE DERIVATIVES

2,3-Dihydroindoles (2,3-Indolines) can be obtained in a highly stereoselective fashion through 1,5-electrocyclization of ortho-substituted aminobenzenes.The scope and mechanism of this novel process are discussed and also some applications.In presence of

Enantioselective 1,5-Electrocyclization. Synthesis of Optically Active Indolines

Intramolecular base-catalysed 1,5-electrocyclization of aldehyde imines derived from o-aminophenyl succinimide (3) in the presence of a chiral alcohol yields chiral indolines (4) with optical purities ranging from 17 to 31percent.
