Treatment of 2-(1,3,5-dithiazinan-5-yl)ethanol (1), 2-(1,3,5-dithiazinan-5- yl)-1-phenylethanol (2), 2-(1,3,5-dithiazinan-5-yl)-1-methylethanol (3) and 2-(1,3,5-dithiazinan-5-yl)-2-methyl-1-phenylethanol (4) with TsCl and NEt 3 in CH2Cl2 afforded the corresponding 3-tosyl-1,3-oxazolidine derivatives (5-8), whereas tosylation of 1-4 in the presence of NHMe3Cl gave the corresponding O-tosyl-2-(1,3,5- dithiazinan-5-yl)ethanol derivatives (11-14). The direct preparation of 5 and 7 from formaldehyde and N-tosylethanolamine (9) or N-tosyl-2-propanolamine was not successful. Reactions of 1 or 3 with benzylamine furnish 1,3,5-tribenzyl-1,3,5- triazinane. Heating of 1 and 2 affords the corresponding 1,3,5-tri(2- hydroxyethyl)-1,3,5-triazinanes. X-Ray diffraction studies of compounds (1-9 and 11) are reported.

A series of boric esters, phosphites, phosphates, thiophosphates and selenophosphates derived from 2-(1,3,5-dithiazinan-5-yl)-ethanol (1), 2-(1,3,5-dithiazinan-5-yl)-1-methyl-ethanol (2), and 2-(1,3,5-dithiazinan-5-yl)- 1-phenylethanol (3) are reported. Enantiopure compounds (C3 symmetry) were prepared from 2(-) and 3(-) of (R) configuration. The new tripodal molecules were viscous liquids which were mainly characterized by 1H, 13C, 11B, 31P, 77Se, NMR and VT-NMR experiments. BH3, BCl3, pyridine and PPh3O adducts of boric esters as well as the BH3 adducts of phosphites were synthesized. The molecular geometries were calculated by HF/6-31G(d). The modeled molecules indicated a preferred ligand conformation which led to the formation of cavities. The complex NMR spectra of isomers were interpreted by comparison with the calculated geometries.
