Modular Continuous Flow Synthesis of Imatinib and Analogues
摘要:
A modular continuous flow synthesis of imatinib and analogues is reported. Structural y diverse imatinib analogues are rapidly generated using three readily available building blocks via a flow hydration/chemoselective C-N coupling sequence. The newly developed continuous flow hydration and amidation modules each exhibit a broad scope with good to excellent yields. Overall, the method described does not require solvent switches, in-line purifications, or packed-bed apparatuses due to the judicious manipulation of flow setups and solvent mixtures.

A method for preparing a functionalized polymer, the method comprising the steps of: (i) polymerizing monomer with an anionic initiator to form a reactive polymer; and (ii) reacting the reactive polymer with a nitrile compound containing a protected amino group, where the protected amino group is directly attached to a moiety selected from the group consisting of acyclic moieties, heterocyclic moieties, and non-aromatic cyclic moieties.
