  Mercaptoacyl aminoacid inhibitors of atriopeptidase. 1. Structure-activity relationship studies of methionine and S-alkylcysteine derivatives

  摘要：

  A broad series of N-(3-mercaptoacyl) amino acid derivatives was evaluated for their ability to inhibit atriopeptidase (neutral endopeptidase, EC 3.4.24.11) in vitro and in vivo. Structural parameters studied were (i) the substituent on the 2-position of the 3-mercaptopropionyl moiety, (ii) the amino acid component, (iii) the S-terminal derivative, and (iv) the C-terminal derivative. Optimum activity was observed for derivatives of methionine and S-alkylcysteines. N-[3-Mercapto-2(S)-[(2-methylphenyl)methyl]-1-oxopropyl]-L-methionine was identified as a highly effective inhibitor of atriopeptidase meriting evaluation as a potential cardiovascular therapeutic agent.

  Dialkyl amides of L-valine, L-isoleucine, and L-tert-leucine (2) are excellent chiral auxiliaries for the construction of quaternary stereocenters at ambient temperature. Enaminoesters 3, prepared from these auxiliaries 2 and Michael donors 1, undergo a copper-catalyzed asymmetric Michael reaction with methyl vinyl ketone (MVK, 4) to afford products 5 in 70-90% yield and 90-99% ee (enantiomeric excess)

  An improved method has been developed for the efficient synthesis of stable camphor imine salts. Camphor imine readily undergoes transimination with α-amino acid ester hydrochlorides to yield camphorylidene amino acid derivatives with E stereochemistry about the CN double bond. Sodium cyanoborohydride reduction of the derived ketimines gives exo-bornylamines.

  cooperative catalysis approach for the enantioselective formal [3+2] addition of α,β‐unsaturated aldehydes to isatins has been developed. Homoenolate annulations of β‐aryl enals catalyzed by an N‐heterocyclic carbene (NHC) require the addition of lithium chloride for high levels of enantioselectivity. This NHC‐catalyzed annulation has been used for the total synthesis of maremycin B.
