Abstract: | On reacting the simple 1,2-amino alcohol: 2-amino-2-methylpropan-1-ol, with borane methyl sulfide (BMS), the expected five member oxazaborolidine ring is not obtained. Instead, two polycyclic structures with trigonal boron atoms 6 and 7 were obtained, and their structure were determined by X-ray crystallography. Compound 6 was obtained in 39% yield and compound 7 was obtained in 7% yield. |
