摘要：

In the present contribution, the boroxazolidones prepared from L-ornithine, L-methionine, kainic acid and 2,6-pyridinedicarboxylic acid have been studied by X-ray crystallography. A comparison of the structural data with corresponding boroxazolidines, bicyclic boronates and tricyclic berates has shown that in boron complexes with a boroxazolidone ring the B-O bond is longer in comparison to boron complexes with a boroxazolidine ring. At the same time the N-->B bond length is shorter indicating that the hydrolytic stability of the complexes with boroxazolidone rings is enhanced. (C) 1998 Elsevier Science S.A. All rights reserved.
