The synthesis of pyrimidinone containing bisheteroarenes (3) and related analogs (9 and 10) by the reaction of active methylenes or substituted methyl acrylate with nitrogen containing precursors viz. amidines, or thiourea in water as well as other organic solvents was studied. Synthesized compounds have further been explored for the synthesis of diversified pyrimidines 4, 6–8, 11, 12 and 14 through
A series of novel N-methyl morpholine (Nmm) based ionic liquids with 1,2-propanediol group were synthesized and used as catalysts for Knoevenagel condensation at roomtemperature in water. Under the effect of the catalyst, various aldehydes or aliphatic ketones could react with a wide range of activated methylene compounds well, including malononitrile, alkyl cyanoacetate, cyanoacetamide, β-diketone

The invention is drawn to a universal method for preparing DNA samples for genotyping of single nucleotide polymorphisms (SNP), deletions and insertions by mass spectrometry. The invention relates to a method for genotyping that comprises three steps:
a. reducing the complexity of the genome,
b. generating allele specific products,
c. analyzing the products by mass spectrometry.
