The Chemistry of Diborane and Sodium Borohydride. XI. The Reaction of Isoquinoline Reissert Compounds with Sodium Borohydride

Chemical and Pharmaceutical Bulletin, 1974
N-Benzenesulfonyl Reissert compound was converted to isoquinaldonitrile with sodium borohydride under very mild reaction conditions and also the N-benzoyl Reissert compound underwent the reductive fission with sodium borohydride. The latter was applied to the synthesis of 1-alkylisoquinolines.
