In a flow microreactor, aryllithiums bearing a piperidylmethyl group were generated using nBuLi by precise residence time control and effective temperature control, and then selectively borylated with boronic esters such as 2-isopropoxy-4,4,5,5-tetramethyl-1,3,2-dioxaborolane (BpinOiPr) and trimethyl borate B(OMe)3 by fast mixing. Moreover, the direct integration with Suzuki–Miyaura cross coupling were successfully achieved to obtain nitrogen-containing biaryl compounds. The present method could be applied for the straightforward synthesis of the key intermediate of a bioactive component bearing a piperidylmethyl-biphenyl framework.

PdII-catalysed ortho-arylation of benzylic heterocycles with arylboronic acid pinacol esters (Ar-BPin) via directed C-H bond activation to generate the desired biaryl products is reported. This methodology is efficient and applicable to a wide range of functionalised Ar-BPin and benzylic heterocycles, allowing the direct synthesis of important biaryl motifs in modest to good yield.

A series of tetrahydroisoquinolines acting as dual serotonin transporter inhibitor/histamine H3 antagonists is described. The introduction of polar aromatic spacers as part of the histamine H3 pharmacophore was explored. A convergent synthesis of the final products allowing late stage introduction of the aromatic side chain was developed. In vitro and in vivo data are discussed.
