    摘要:
    The chemoselective and diastereoselective hydrogenation of 2,3-dibydro-3-[(S)-alpha-methylbenzyl]-4-quinazolinone 2 affords octahydroquinazolinones cis-3 and cis-4. Epimerization of cis-3 and cis-4 using t-BuO-K+ produces trans-5 and trans-6, respectively. Hydrolysis with HCl of these octahydroquinazolinones leads to the free, enantiomerically pure, cis- and trans-2-aminocyclohexane-1-carboxylic acids 7-10. (C) 2004 Elsevier Ltd. All rights reserved.

  • Glyoxylic acid in the reaction of isatoic anhydride with amines: a rapid synthesis of 3-(un)substituted quinazolin-4(3H)-ones leading to rutaecarpine and evodiamine

    A dual reactant/catalyst role of glyoxylic acid in the reaction of isatoic anhydride with various amines afforded a novel, robust and rapid synthesis of 3-(un)substituted quinazolin-4(3H)-ones. This metal catalyst-free reaction proceeds via an unusual and unexpected cleavage of C–C bond. A shorter and common route to two alkaloids, that is, rutaecarpine and evodiamine is also accomplished.

    before their NMR spectra in CDCl3 solutions were recorded. The detection of the low energy conformation of O=C-N-phenethyl segment in solution allowed the correlation of the NMR data with the configuration of newly stereogenic carbon C-2; thus, one diastereomer was labeled SS while the other was RS. Configurations determined by the NMR method were corroborated by X-ray diffraction analysis. X-ray structures
