摘要:
The development of an alternative synthetic route to a functionalized imidazopyridazine which strategically streamlines the synthesis and avoids a number of problematic reagents is described. Key to the success of this alternative route is the use of two C-H functionalization reactions: a Pd-catalyzed direct benzylation reaction to functionalize a C-H bond with a substituted benzyl group and a V-catalyzed NMO addition reaction to install a benzylic morpholine moiety.
