  摘要：

  The reduction of 1-acetylamino-3-methylisochromene-4-carbonitrile and an N-butyl-1, 2-dihydroisoquinoline analogue with sodium borohydride and sodium cyanoborohydride in ethanol and carboxylic acid media are reported. Ready reduction at the 1-position occurred, followed by further reductive loss of the acetylamino group so formed. The ease of reduction of the 3,4-double bond was different for the O- and N-series but conditions were established for preparation of the fully reduced species. Sodium borohydride with cobalt chloride in methanol was effective at reducing the cyano function.

  Abstract The product from the diacetylation of α-cyano-o-tolunitrile has now been assigned as an isocoumarin derivative. This is readily transformed into various 1-substituted-3-methylisoquinoline-4-carbonitriles by reaction with oxygen, nitrogen, carbon and hydrogen nucleophiles.
