An effective microwave-assisted urea formation from cyclopentyl- or isopropyl-substituted ureas is described. This novel transamidation methodology provided ureas IIa–IIq in good yields via microwave irradiation of the cyclopentyl- or isopropyl-substituted ureas with excess (5–10 equiv) of amines at 150 °C in THF/DMSO.
描述了由环戊基或异丙基取代的脲有效形成微波辅助的脲。通过在THF / DMSO中在150°C下用过量(5-10当量)胺进行微波辐射,通过微波辐照环戊基或异丙基取代的脲,这种新颖的转酰胺方法可以提供高收率的脲IIa – IIq。
