The one-pot (three steps) synthesis of α-diazo-β-hydroxyesters from tosyl chloride under phase-transfer catalysis is described. The catalytic asymmetric aldol reaction between a diazoester and aldehydes was also investigated and gave moderate to good enantioselectivity.
描述了在相转移催化下由甲
苯磺酰氯一锅(三步)合成α-重氮-β-羟基酯。还研究了重氮酯与醛之间的催化不对称醛醇缩合反应,并给出了中等至良好的对映选择性。
