  • Highly enantioselective Biginelli reaction catalyzed by SPINOL-phosphoric acids
    作者:Fangxi Xu、Dan Huang、Xufeng Lin、Yanguang Wang
    DOI:10.1039/c2ob25663k
    日期:——
    A highly enantioselective Biginelli reaction promoted by chiral spirocyclic SPINOL-phosphoric acids has been developed. Under the optimized conditions with 5 mol% catalyst loading, a wide range of optically active dihydropyrimidinethiones (DHPMs) were obtained in high yields (up to 98%) with good to excellent enantioselectivities (up to 99% ee). The synthetic utility of this method was demonstrated

  • Chemical resolution of inherently racemic dihydropyrimidinones via a site selective functionalization of Biginelli compounds with chiral electrophiles: a case study

    ‘hardness or softness’ of the metalated site/electrophile used. Biginelli dihydropyrimidinone substrate appended with enantiopure N-protected l-phenylalanine amino acid chloride, at N-3 position after resolution and deprotection yielded both enantiomers of 3,4-dihydropyrimidinones.

    A practical and short synthesis of the enantiomerically pure dihydropyrimidone antitypertensive agent (R)-SQ 32926 has been developed. The key step in the synthesis is the enzymatic resolution of an N3-acetoxymethyl-activated dihdropyrimidone precursor by Thermomyces lanuginosus lipase. The absolute configuration of (R)-SQ 32926 was confirmed by circular dichroism spectroscopy. (C) Elsevier Science Ltd. All rights reserved.
  • Synthesis and reactions of Biginelli-compounds. Part 23. Chemoenzymatic syntheses of enanttiomerically pure 4-aryl-3,4-dihydropyrimidin-2(1H)-ones
    作者:Barbara Schnell、Wolfram Krenn、Kurt Faber、C. Oliver Kappe
    DOI:10.1039/b006372j
    日期:——
    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 by various lipases in two different solvent systems with selectivities E < 50. Alternatively, attachment of an acetoxymethyl residue at the N3 position of the DHPM scaffold led to activated ester 15, which was selectively cleaved by Thermomyces lanuginosus lipase (E > 200) to furnish, after deprotection, DHPMs (R)- and (S)-13 on a semi-preparative scale. Treatment of (R)-13 with trichloroacetyl isocyanate produced the antihypertensive agent (R)-SQ 32926.
