| Abstract: | Acid-catalyzed acylation of 3,4-dimethoxyphenylacetone with  -chlorobutyryl chloride gave 1-(3-chloropropyl)-6,7-dimethoxy-3-methylbenzoc]pyrylium perchlorate. Recyclization of the product with nitrogen nucleophiles (ammonia, primary amines, hydrazine derivatives, hydroxylamine) led through the corresponding isoquinolinium salts to benzof]indolizinium, pyridazino2,1-b]isoquinolinium, and 1,2-oxazino2,1-b]isoquinolinium salts. |
| Keywords: | 3 4-dimethoxyphenylacetone 1-(3-chloropropyl)-6 7-dimethoxy-3-methylbenzo[c]pyrylium |
