3,3-Disubstituted tetrahydroisoquinolines are prepared in one step from Michael acceptors and 2-phenylethylamines under Pd catalysis and Ag2CO3 as an oxidant. Presumably, activation of an ortho C-H bond of the aromatic ring with Pd(II) is directed by the primary amine to form a palladacycle. Insertion of the olefin, subsequent conjugated addition of the amine, and reductive elimination of Pd(0) affords the expected products. Silver carbonate is not necessary when 2-phenylethylamines are converted previously to N-benzoyloxy-2-phenylethylamines.

Substituted 1-(aminomethyl)-2-(arylacetyl)-1,2,3,4- tetrahydroisoquinolines: A novel class of very potent antinociceptive agents with varying degrees of selectivity for κ and μ opioid receptors

This study describes the synthesis of a series of novel substituted 1- (aminomethyl)-2-(arylacetyl)-1,2,3,4-tetrahydroisoquinolines, and discusses their structure-activity relationships (SARs) using binding affinity for opioid receptors and antinociceptive potency as the indices of biological activity. The introduction of a hydroxy substituent in position 5 of the isoquinoline nucleus generated a compound, 40, which is 2 times more potent than the previously disclosed unsubstituted analogue 39 in mouse models of antinociception. A QSAR analysis of the 5-substitution clearly demonstrates that antinociceptive activity is inversely associated with the lipophilicity of the substituents. The substituted compounds described herein are less selective for the κ opioid receptors than the unsubstituted isoquinoline 39. For example, the 5-hydroxy-substituted compound 59 shows high affinity for κ opioid receptors (K(i) κ = 0.09 nM) and a (K(i) μ/K(i) κ ratio of only 5. However, a multiple linear regression analysis demonstrates a lack of correlation between antinociceptive activity and affinity for the μ opioid receptor. On the other hand, the correlation between binding affinity to κ opioid receptor and antinociceptive activity was statistically significant.
