Synthesis and radioligand binding studies of bis-(8-isopropyl-isoquinolinium) derivatives as ligands for apamin-sensitive sites on cloned SK2 and SK3 channels

A metal-free cyclic iminium induced one-pot double annulation cascade: access to dihydroisoquinolinium (DHIQ) salts

A reactive cyclic iminium induced one-pot Groebke–Blackburn–Bienayme (GBB) double annulation cascade (DAC) for the synthesis of skeletally diverse DHIQ salts has been described. The key features of this protocol are solvent-free, robust method, clean reaction profile and operational simplicity.

Rh(iii)-catalyzed synthesis of 1-substituted isoquinolinium salts via a C–H bond activation reaction of ketimines with alkynes

An efficient synthesis of highly substituted isoquinolinium salts from ketimines and alkynes via a Rh(iii)-catalyzed C–H bond activation and annulation reaction is described.
