N2 - The synthesis of 1,3,2-thiazaborolidine and 2,3-dihydro-2,1,3-borathiazolidines from reaction of ephedrine disulfide and 3,4-dimethyl-5-phenyl-1,3-thiazolidine-2-thione with BH3-THF is reported. The two reactions afforded optically active borohydride heterocycles. The X-ray diffraction structure of (1R,2R)-(-)-chlorodeoxy-pseudo-ephedrine hydrochloride, (1R,2R)-(-)-thiosulfonic ddeoxy-pseudo-ephedrine and (3S,4R,5R)-(+)-dihydro-3,4-dimethyl-5-phenyl-2,1,3-borathiazolidine are reported.
