MoOPH oxodiperoxymolybdenum pyridine hexamethylphosphoric triamide

HYDROXYLATION OF ENOLATES WITH OXODIPEROXYMOLYBDENUM(PYRIDINE)-(HEXAMETHYLPHOSPHORIC TRIAMIDE), MoOc-Py-HMPA (MoOPH) ... [Pg.227]

Enolate Hydroxylation. Treatment of the sodium enolates with the Davis oxaziridine reagent affords the hydroxylated products with the same sense of induction as the alkylation products (eq 23). Although high diastereoselectivity may be achieved with Oxodiperoxymolybdenum(pyridine)(hexamethylphosphoric triamide) (MoOPH), such reactions proceed in lower yields. [Pg.60]

Oxodiperoxymolybdenum-pyridine-hexamethylphosphoric triamide, MoOj CjHsN-HMPA (MoOPH), which is prepared from molybdenum trioxide, M0O3 [531,532], hydroxylates the enolates of ketones and esters in the a position with respect to the carbonyl groups [537, 532, 533] and, in the presence of mercuric acetate, converts acetylenes into a-dicarbonyl compounds [534].
