A mild and efficient one-pot visible light-induced method has been developed for the trifluoromethylation of disubstituted morpholines. This method includes synthesis of substituted 4-tosyl-5-[(trifluoromethyl)thio]morpholine 4(a-l) from tosylaziridine 1(a-l) and oxiran-2-thiol (2) in presence of eosin Y as an organophotoredox catalyst at room temperature under aerobic condition.
开发了一种温和且高效的一锅法可见光诱导三氟甲基化二取代吗啉的方法。该方法包括在室温下、好氧条件下,以光敏有机催化剂伊红Y为催化剂,从托斯基唑烯1(a-l)和二氢噻唑-2-硫醇(2)合成取代的4-托烯基-5-[(三氟甲基)硫]吗啉4(a-l)。
