Ringopening of oxazolidines derived from tris(hydroxymethyl)aminomethane, l-serine and l-threonine was investigated. It was shown that n(N)→σ∗(C–O) electron delocalization (endo-anomeric effect) occurring in the five-membered ring plays a major role in the cleavage of the intracyclic C–O bond. The present work establishes that when the nitrogen lone pair is conjugated with a carbonyl group (n(N)→π(CO)

An effective synthetic strategy for the amino-containing organic derivative of hexavanadate, TBA2[V6O13(OCH2)3CNH2}2], is presented. By using this method, the yield is increased extremely and crystals of the intermediate and cation-exchanged products are both obtained and structurally characterized via single-crystal X-ray diffraction, IR and 1H-NMR.
