1-Bn-DHIQs to 1-Bz-DHIQs without concomitant excessive oxidation of 1-Bz-DHIQs to 1-Bz-IQs is very important for the syntheses of 1-Bz-DHIQ alkaloids and analogues. In this article, we developed a novel Cu(ii)-catalyzed and acid-promoted highly regioselective oxidation of tautomerizable C(sp3)-H bonds adjacent to the C-1 positions of various 1-Bn-DHIQs. It was observed that when 0.2 equiv. of Cu(OAc)2·2H2O

We describe here the synthesis and evaluation of a series of tetrahydroisoquinolines that show subunit-selective potentiation of NMDA receptorscontaining the GluN2C or GluN2D subunits. Bischler–Napieralski conditions were employed in the key step for the conversion of acyclic amides to the corresponding tetrahydroisoquinoline-containing analogs. Compounds were evaluated using both two-electrode voltage

The disclosure concerns novel enantiomers of tetrahydroisoquinoline derivatives and their pharmaceutically acceptable salts, their preparations and pharmaceutical compositions. The enantiomers of tetrahydroisoquinoline derivatives are provided which are useful in stimulating heart rate and hypotensive activity, inhibitory activity against platelet aggregation, and suppressive against inducible NO synthase. The enantiomers of tetrahydroisoquinoline derivatives and their pharmaceutically acceptable salts are effective for treating congestive heart failure, hypertension, thrombosis, inflammation, septicemia, cardiac insufficiency, and disseminated intravascular coagulopathy.

N‐Dealkylation methods are well described for organic chemistry and the reaction is known in nature and drug metabolism; however, to our knowledge, enantioselective N‐dealkylation has not been yet reported. In this study, exclusively the (S)‐enantiomers of racemic N‐ethyl tertiary amines (1‐benzyl‐N‐ethyl‐1,2,3,4‐tetrahydroisoquinolines) were dealkylated to give the corresponding secondary (S)‐amines
