A variety of 3‐substituted and 2,3‐disubstituted indoles were synthesized efficiently in good yields through the intramolecular amination of 2‐alkenylanilines promoted by readily available iodine(III) reagents in a short reaction time. Mechanistic studies showed that the reaction pathway went through a nitrenium ion and that 3‐acetoxy indoline was the key intermediate in the indole formation. The indole

The present invention provides a method for producing a 4,4,7-trifluoro-1,2,3,4-tetrahydro-5H-1-benzazepine compound which has an superior agonistic activity to an arginine vasopressin V2 receptor and is useful as an active ingredient for a pharmaceutical composition for preventing and/or treating urinary frequency, urinary incontinence, enuresis, central diabetes insipidus, nocturia, nocturnal enuresis, or the like; and useful intermediates for use in the methods. The production method of the present invention is suitable for the industrial production of a medicament, because of a smaller number of steps, a higher yield, and a lower cost, as compared with the methods in the related art.

unprecedented γ-(hetero)aryl/alkenyl-δ-silyl aliphatic amines via silyl-mediated distal (hetero)aryl/alkenyl migration of aromatic/alkenyl amines bearing unactivated alkenes with hydrosilanes. This protocol features mild and metal-free reactionconditions, high atom economy, excellent selectivity, and functional group compatibility. Mechanistic studies suggest that silylation and (hetero)aryl/alkenylation
