An expedient synthesis of oxazepino and oxazocino quinazolines
摘要:
A synthetic route to a new class of privileged tri- and tetra-cyclic quinazolines containing a medium-sized ring is reported. An expedient synthetic route involving nucleophilic aromatic substitution, and sequential Niementowski and BOP-mediated ring closures afforded a collection of analogues. The scope of the reaction was explored in terms of cyclic and acyclic linkers, ring size and substitution pattern. (C) 2015 Elsevier Ltd. All rights reserved.
