Popis: Alkylation of 3-methyl-1-isoquinolone and 1-methyl-3-isoquinolone with phenacyl bromides proceeds regioselectively with the formation in the first case of only an N-phenacyl derivative and in the second only the O-derivative. The 5-methyl[1,3]oxazolo[3,2-a]isoquinolinium salt has been synthesized and its reactions with ammonia, morpholine, and sodium methylate have been investigated.
