SYNTHESIS AND REACTIONS OF 1-(3-CHLOROPROPYL)-6,7-DIMETHOXY-3-METHYLBENZO[<i>c</i>]PYRYLIUM PERCHLORATE
Keywords:
3,4-dimethoxyphenylacetone, 1-(3-chloropropyl)-6,7-dimethoxy-3-methylbenzo[c]pyrylium, γ-chlorobutyryl chloride, recyclizationAbstract
Acid-catalyzed acylation of 3,4-dimethoxyphenylacetone with γ-chlorobutyryl chloride gave 1-(3-chloropropyl)-6,7-dimethoxy-3-methylbenzo[c]pyrylium perchlorate. Recyclization of the product with nitrogen nucleophiles (ammonia, primary amines, hydrazine derivatives, hydroxylamine) led through the corresponding isoquinolinium salts to benzo[f]indolizinium, pyridazino[2,1-b]-isoquinolinium, and 1,2-oxazino[2,1-b]isoquinolinium salts.
