Facile synthesis of pyrimidines via iminium catalyzed [4+2] reaction of α,β-unsaturated ketones with 1,3,5-triazines
摘要:
[4+2] cycloaddition of alpha,beta-unsaturated ketones with 1,3,5-triazine via iminium catalysis has been developed. This method could finish pyrimidines in high levels of regioselectivity and with good yields. (C) 2015 Elsevier Ltd. All rights reserved.
