Chemical resolution of inherently racemic dihydropyrimidinones via a site selective functionalization of Biginelli compounds with chiral electrophiles: a case study
Lithiation/substitution of 4-aryl-6-methyl-3,4-dihydropyrimidin-2(1H)-one ester derivatives with n-BuLi can be directed selectively at N-3 or C-6 positions, depending upon nature and equivalents of the base used and 'hardness or softness' of the metalated
