We have demonstrated that chiral 1-(1,3-dithian-2-yl)prop-2-en-1-ols as new scaffolds, obtained by enzyme-catalyzed kinetic resolution, undergo Suzuki-Miyaura cross-couplings and hydroformylation smoothly. Also, we have found that a 1,3-dithianyl group of the products can be removed without any erosion of the enantiopurity under mild conditions.

我们已经证明,通过酶催化动力学拆分获得的手性1-(1,3-二硫-2-基)丙-2-烯-1-醇作为新型支架,可以顺利进行Suzuki-Miyaura交叉偶联和加氢甲酰化反应。而且,我们发现在温和条件下,可以除去产物的1,3-二噻吩基,而对映体纯度没有任何侵蚀。描述了一种新的途径,可确保绝对构型的多种对映纯α-羟基醛。
