Uses

Research has demonstrated that the Niementowski quinazoline synthesis could be employed for the creation of potential EGFR-inhibiting molecules. Hensbergen et al.[4] have shown a synthetic route to a new class of privileged tri- and tetra-cyclic quinazolines containing a medium-sized ring.

A nucleophilic aromatic substitution is combined with the Niementowski reaction and a BOP-mediated ring closure to afford several analogues.
