摘要:
The direct coupling of sp(3) C-OH bond of N -heterocyclic aminols with sp(2) C-H bond of electron rich arenes have been achieved via iron catalyzed dehydrative cross coupling strategy. This novel protocol provides an efficient and straight forward route to access biologically important C4-aryl-3,4dihydroquinazoline derivatives through the reaction of C4-hydroxy-3,4-dihydroquinazolineiaminol with phenol and aniline derivatives under mild reaction conditions.
