SpletCatalytic tetra- N -propylammonium perruthenate (TPAP) oxidation of alcohol 84 followed by filtration through a pad of silica gel to remove morpholine and ruthenium by-products gave an intermediate aldehyde which was immediately oxidised to the corresponding acid using a previously developed modified Pinnick procedure [ 14 ]. SpletN-Methylmorpholine-N-oxide or NMO is an organic compound. This heterocyclic amine oxide and morpholine derivative is used in organic chemistry as a co-oxidant and sacrificial catalyst in oxidation reactions for instance in osmium tetroxide oxidations and the Sharpless asymmetric dihydroxylation or oxidations with TPAP.
