Abstract
The polymer assisted solution phase (PASP) synthesis of 4,5-dihydro-1,4-benzoxazepin-3(2H)-ones is described. Using salicylic aldehydes, alpha-bromo acetic acid esters, and primary amines as broadly variable building blocks, the target molecules were obtained in a straightforward manner. The use of polymer bound reagents and scavengers greatly simplified workup, and avoided the use of protecting groups. A small library was prepared, showing the feasibility of the synthetic concept for the generation of larger sets of screening compounds.
