Cyclisation of 1,2-dioxines containing tethered hydroxyl and carboxylic acid functionality: Synthesis of tetrahydrofurans and dihydrofuran-2(3H)-ones
Herein we outline cyclisations of tethered hydroxyl and carboxylic acid moieties onto the olefinic motif of 1,2-dioxines to generate tetrahydrofurans and dihydrofuran-2(3H)-ones, whilst maintaining the peroxide linkage intact. This work demonstrates the first examples of intramolecular cyclisation o...
