Highly-functionalized pyrroles could be effectively synthesized from 3,6-dihydro-1,2-oxazines using a heterogeneous copper on carbon (Cu/C) under neat heating conditions. Furthermore, the in situ formation of 3,6-dihydro-1,2-oxazines via the hetero Diels–Alder reaction between nitroso dienophiles and 1,3-dienes and the following Cu/C-catalyzed pyrrole synthesis also provided the corresponding pyrrole derivatives
可以在纯净的加热条件下,使用非均相的碳载铜(Cu / C),从3,6-二氢-1,2-恶嗪有效地合成高度官能化的吡咯。此外,原位形成的3,6-二氢-1,2-恶嗪经由亚硝基的亲二烯体和1,3-二烯和以下的Cu / C催化的吡咯合成还提供了相应的吡咯衍生物之间的杂Diels-Alder反应以一锅的方式。
