Abstract: Phosphine oxide-Sc(OTf)3 catalyzed regio- and enantioselective bromoaminocyclization of tri-substituted allyl N-tosylcarbamates is described. A wide variety of optically active tertiary 5-bromo-1,3-oxazinan-2-ones can be obtained with high regio-and enantioselectivity. read more here.

Abstract: A new synthetic approach to tri-substituted trisalkoxy-hexavanadate clusters containing different organic groups was developed in this work. Four mixed-valence or fully reduced POV hybrids were synthesized and structurally characterized, including an amino-containing derivative of hexavanadate,… read more here.
