Light-mediated deoxygenation of alcohols with a dimeric gold catalyst

A new protocol for the reductive deoxygenation of primary alcohols was explored. This photo-mediated method combines a novel approach to bromination of alcohols merged with the powerful reducing capability of [Au2(dppm)2]Cl2 [dppm = 1,1-bis(diphenylphosphino)methane] as a photoredox catalyst. The highly efficient methods discussed are marked by the use of UVA light-emitting diodes, which have significantly reduced reaction times and lowered setup cost.

VERSATILE METHODS OF SYNTHESIS OF 5 TO 8-MEMBERED RING N-HETEROCYCLES VIA INTRAMOLECULAR CYCLOADDITIONS OF ALLYLAMINES

N-Tosylallylamines or homoallylamines were monoalkylated with dibromoalkanes to produce bromoalkylamines 3 or 7.The latter were converted to unsaturated nitro derivatives which, via nitrile oxides, underwent intramolecular cycloaddition to form hetero rin
