Synthesis of β-Keto Esters In-Flow and Rapid Access to Substituted Pyrimidines
摘要:
We have developed an in-flow process for the synthesis of beta-keto esters via the BF3 center dot OEt2-catalyzed formal C-H insertion of ethyl diazoacetate into aldehydes. The beta-keto esters were then condensed with a range of amidines to give a variety of 2,6-substituted pyrimidin-4-ols.
The present invention provides a control agent that is extremely effective in controlling bacterial diseases. The quorum sensing inhibitor and bacterial disease control agent for agricultural and horticultural use of the present invention contain a pyrimidinone compound represented by General Formula (1) :
wherein R1 represents a C1-5 alkyl group or a phenyl group, and R2 represents a hydrogen atom or a C1-5 alkyl group, provided that R1 cannot be a methyl group when R2 represents a hydrogen atom.
