An asymmetric synthesis of 1-deoxynojirimycin (2) mediated by a chiral auxiliary is reported. The dihydropyridone 4 was converted to diol 11 in three steps by acetoxylation, hydrolysis, and stereoselective reduction. Dihydroxylation of 11 followed by catalytic reduction afforded 2.
据报道由手性助剂介导的1-deoxynojirimycin(2)的不对称合成。通过乙酰氧基化,水解和立体选择性还原,在三个步骤中将二氢吡啶酮4转化为二醇11。进行11的二羟基化,然后进行催化还原,得到2。
