A new family of optically active 2,3-dihydrobenzofurans has been prepared by a simple chemoenzymatic asymmetric strategy. This synthetic approach is based on the combination of a lipase-mediated kinetic resolution of 1-aryl-2-propanols or bioreduction of the corresponding ketones followed by an intramolecular cyclization reaction. These novel compounds have been prepared in enantiopure form and in
通过简单的化学酶促不对称策略已经制备了新的旋光的2,3-二氢苯并呋喃家族。这种合成方法是基于脂肪酶介导的1-芳基-2-丙醇的动力学拆分或相应的酮的生物还原,然后进行分子内环化反应的组合。这些新化合物已通过对映纯的形式制备,并通过直接途径以较高的总收率制备。
