Tandem Directed Lithiations of N-Boc-1,2-dihydropyridines toward Highly Functionalized 2,3-Dihydro-4-pyridones
摘要:
Sequential tandem directed lithiations of an N-Boc-4-methoxy-1,2-dihydropyridine have been achieved, leading to C-5,C-6 disubstituted dihydropyridones on acidic workup. The chlorine atom of the dihydropyridone products can in turn be substituted giving rise to diverse substituents at C-6.
