Isoquinolines activated with sulfamoyl chlorides were reacted with indoles in a 3-component reaction to generate a library of dihydroisoquinoline derivatives. Using a differential protecting group strategy, products could be further derivatised. Synthesis of isoquinoline starting materials using several different methods is also described.

The first Pd-catalyzed alkylation of (iso)quinolines and arenes is reported. The readily available and bench-stable 2-acylpyridine compounds were used as an alkylation reagent to form the structurally versatile alkylated (iso)quinolines and arenes. The method affords a convenient pathway for the introduction of alkyl groups into organic molecules.

Dinapsoline is a full D1 dopamine receptor agonist that produces robust rotational activity in the unilateral 6-OHDA rat model. This compound is orally active, and shows a low tendency to cause tolerance in rat models. The active enantiomer was determined to have the S-(+) configuration, and the opposite enantiomer is essentially devoid of biological activity. Taken together, dinapsoline has significant metabolic and pharmacological advantages over previous D1 agonists. In an attempt to define the structure-activity relationships (SARs) and to map out the key elements surrounding the unique structure of dinapsoline, core analogues and substitution analogues of the parent tetracyclic condensed ring structure were prepared. Based on a recently developed synthesis of dinapsoline and its enantiomers, both core and substitution analogues on all four rings (A, B′, C and D ring) of dinapsoline were synthesized. It was found that affinity for both D1and D2 receptors was decreased by most substituents on the A, B′, and C rings, whereas D ring substitutions preserved much of the dopamine receptor binding activity.
