Abstract |
Commercially available silica (SiO2) was found to be highly effective catalyst for one-pot synthesis of -aminoalcohols from olefins via bromohydrins using morpholine as nitrogen fragment donor. Furthermore, silica in the presence of easily accessible N-bromosuccimide (NBS) catalyzes a rapid and quantitative room temperature bromohydroxylation of simple olefins. Various olefins are easily converted to the corresponding vic-bromohydrins and in “one pot” to -aminoalcohols in excellent yields and high selectivity. The reaction offers a simple and efficient method for the preparation of vic-bromohydrins and -aminoalcohools. |
