[New analogs of papaverine: synthesis, pharmacological and conformational study of benzyl-4-isoquinolines substituted in the 1 or 3 position].
The synthesis of p-chlorobenzyl-4-isoquinolines variously substituted in the 1 and 3 positions by condensation in an acid medium of the diethyl acetal of a substituted N-veratrylaminoacetaldehyde with p-chlorobenzaldehyde is described. Pharmacological and conformational tests have been carried in comparison with papaverine and p-chlorobenzyl-4-isoquinoline. The basicities of these derivatives have been measured and compared.
