Highly enantioselective Biginelli reaction using a new chiral ytterbium catalyst: Asymmetric synthesis of dihydropyrimidines

The highly enantioselective three-component Biginelli condensation catalyzed by a recyclable chiral ytterbium triflate with a novel hexadentate amine phenol ligand containing a pyridyl group has been developed. A wide range of optically active dihydropyrimidines with remarkable pharmacological interest was obtained in high yields with good to excellent enantioselectivities under mild conditions. Copyright

Synthesis and reactions of Biginelli-compounds. Part 23: Chemoenzymatic syntheses of enantiomerically pure 4-aryl-3,4-dihydropyrimidin-2(1H)-ones

Enantiomerically pure dihydropyrimidones (DHPMs) were prepared by lipase-catalyzed enzymatic resolution of two types of activated DHPM esters. In the first model series, pivaloyloxymethyl-activated DHPM C5-esters 10a-c were resolved on an analytical scale

Synthesis of enantiomerically pure 4-aryl-3,4-dihydropyrimidin-2(1H)-ones via enzymatic resolution: preparation of the antihypertensive agent (R)-SQ 32926

A practical and short synthesis of the enantiomerically pure dihydropyrimidone antihypertensive agent (R)-SQ 32926 has been developed. The key step in the synthesis is the enzymatic resolution of an N3-acetoxymethyl-activated dihydropyrimidone precursor b

Dihydropyrimidine calcium channel blockers. 3. 3-carbamoyl-4-aryl-1,2,3,4-tetrahydro-6-methyl-5-pyrimidinecarboxylic acid esters as orally effective antihypertensive agents

In order to explain the potent antihypertensive activity of the modestly active (IC50 = 3.2 μM) dihydropyrimidine calcium channel blocker 5, we carried out drug metabolism studies in the rat and found 5 is metabolized to compounds 6-10. Two of
