抄録
Ammonolysis of 3, 4-dihydroisocoumarins to obtain 3, 4-dihydroisocarbostyrils was investigated. Heating of a solution of 8-deoxyphyllodulcin (3) or phyllodulcin (8), a 3, 4-dihydroisocoumarins having a phenyl group substituted at 3-position, in ethanolic ammonia gave the corresponding 3, 4-dihydroisocarbostyrils (1 or 2) and stilbenes (4 and 5 or 9). By the same reaction, agrimonolide (10) an 3-alkyl-3, 4-dihydroisocoumarins, gave only 3-alkyl-3, 4-dihydroisocarbostyril (11). Aminolysis of 3 with methylamine or N, N-dimethylaminoethylamine gave the corresponding 2-(2-N-alkylcarbamoylphenyl)-1-(3-hydroxy-4-methoxyphenyl) ethanols in a high yield, which gave the corresponding 2-alkyl-3, 4-dihydroisocarbostirils (14 or 15) by heating with 50% acetic acid containing 4% sulfuric acid.
