An operationally simple and general method for acetylation and acylation of a wide variety of substrates (amines, alcohols, phenols, thiols, and hydrazones) has been reported. Meldrum's acid and its derivatives have been used as an air-stable, non-volatile, cost-effective, and easy to handle acetylating/acylating agent. Easily separable byproducts (CO2 and acetone) allowed the isolation of analytically pure acetylated products without the requirement of work-up and any chromatography. This journal is
Facile synthesis of novel pyrimido[1,2-a]pyrimidin-4-ones from highly reactive malonates

experimental part, p. 2113 - 2120 (2010/06/15)
A very simple and efficient procedure for the synthesis of novel 2-hydrox.y-4H-pyrimido[1,2-a]pyrimidin-4-ones is described. Title compounds were obtained from the room temperature reaction of 2-aminopyrimidine and its substituted derivatives with bis(2,4,6-trichlorophenyl) malonates. High product yields were observed under optimized conditions. Applicability and reactivity of a range of substituted and unsubstituted phenyl malonates were also investigated. Structural identification of all new compounds was accomplished by spectroscopic methods and elemental analysis.
