A straightforward route to polyols, amino polyols, polysubstituted lactols and lactones from readily available arenes has been devised. It uses a three- or four-step sequence involving a Birch reduction of the arene, followed by desymmetrization through dihydroxylation or aminohydroxylation and, lastly, ozonolysis of the remaining olefin. Depending on the ozonolysis workup conditions, cyclic or acylic
已经设计了从容易获得的芳烃制备多元醇、氨基多元醇、多取代的内酯和内酯的直接途径。它使用三步或四步序列,包括芳烃的 Birch 还原,然后通过二羟基化或氨基羟基化进行去对称化,最后是剩余烯烃的臭氧分解。取决于臭氧分解后处理条件,环状或酰基合成子通常以较高的总产率和出色的立体控制水平获得。(© Wiley-VCH Verlag GmbH, 69451 Weinheim, Germany, 2002)
