Reduction and N-alkylation of α-methylene-indolines with sodium cyanoborohydride in carboxylic acids

Balogh,Zsadon,Csampai,Pal

, p. 701 - 707 (1994)

The reaction of α-methylene-indolines with NaCNBH3 in carboxylic acids at room temperature can yield either 2β,3β-dihydro-indolines or their N- alkyl derivatives as main products with high selectively, depending mainly on the carboxylic acid and on the reaction time when using a large excess of NaCNBH3.
