A new Rh-catalyzed, three-component reaction for the oxytrifluoromethylthiolation of α-diazoketones was developed. The SCF3 functionality was introduced using a stable dibenzenesulfonimide reagent under mild conditions. Alcohols, acetals, and ethers were used as the alkoxy sources. Cyclic ethers underwent a trifunctionalization reaction through the introduction of SCF3, OR, and N(SO2Ph)2 substituents
开发了一种新的Rh催化的三组分反应,用于α-重氮酮的三氟甲基硫氧基化反应。使用稳定的二苯磺酰亚胺试剂在温和条件下引入SCF 3官能度。醇,缩醛和醚用作烷氧基源。通过在单个步骤中引入SCF 3,OR和N(SO 2 Ph)2取代基,使环醚进行三官能化反应。
