conditions were developed and the optimal temperature regime was selected for a selective thionation of 5-aryl-3-[(dimethylamino)-methylidene]furan-2(3H)-ones with Lawesson's reagent. The stereochemistry of the synthesized 3-[(dimethylamino)methylidene]furan-2(3H)-thiones was established. Based on this, a number of 3-arylaminomethylidenefuran-2(3H)-thiones were synthesized via transamination reaction
开发了使用 Lawesson 试剂选择性硫化 5-芳基-3-[(二甲基氨基)-亚甲基]呋喃-2(3H)-酮的条件并选择了最佳温度方案。建立了合成的3-[(二甲基氨基)亚甲基]呋喃-2(3H)-硫酮的立体化学。在此基础上,通过氨基转移反应合成了多种3-芳氨基亚甲基呋喃-2(3H)-硫酮。
