  Angiotensin-converting enzyme inhibitors. Perhydro-1,4-thiazepin-5-one derivatives

  摘要：

  alpha-[6-[[(S)-1-(Ethoxycarbonyl)-3-phenylpropyl]amino]-5-oxoperhydro -1,4-thiazepin-4-yl]acetic acids (monoester monoacids) and their dicarboxylic acids having the hydrophobic substituents at the 2- or 3-position of the thiazepinone ring were prepared and assayed for angiotensin-converting enzyme (ACE) inhibitory activity. The dicarboxylic acids having the pseudoequatorial amino groups at the 6-position and the pseudoequatorial hydrophobic substituents at the 2- or 3-position of the chair conformation of the thiazepinone ring had potent in vitro inhibitory activity. The monoester monoacids having the hydrophobic substituents at the 2-position suppressed pressor response to angiotensin I for a longer duration than those having the substituents at the 3-position when administered orally. The structure-activity relationship was studied by conformational energy calculations of the thiazepinone ring.

  Eu(fod)3 catalyzed [4+2] heterocycloadditions of para-methoxystyrene 7 with esters 8a-f of benzylidenepyruvic acids (deriving from various chiral alcohols) furnished endo adducts 9a-f with variable diastereoselective ratios (from to ). Interestingly, the benzylidenepyruvic esters 8g and 8h, deriving from a new chiral vector, the α-O-silyl ether 6 of (D)-(−)-erythronolactone 5, gave the corresponding

• Synthèse asymétrique et configuration absolue de dihydropyranes substitués, par hétérocycloaddition intermoléculaire d'éthers vinyliques chiraux

  日期：1994.1

  The alkyl vinyl ethers 2b-8b (deriving from the alcohols 2a-8a) smoothly reacted with methyl E-benzylidenepyruvate 10 in the presence of catalytic amounts of Eu(fod)(3) or Yb(fod)(3) in refluxing hexane, thus leading to the dihydropyran endo adducts 13-19 in high yields (80-95%). The endo-cycloadducts 13-17 were obtained with diastereofacial selectivities (ds) ranging from 76/24 to 87.5/12.5. Asymmetric induction was found to culminate with the vinyl ether (-)-7b deriving from n-butyl (R)-(-)-mandelate : the best ds (92.5/7.5) was obtained for the corresponding adduct 18 after 6 days at room temperature. The absolute configurations of the major isomers of the dihydropyrans 16-18, 20 and 21 were established by oxydative degradation to optically active alpha-phenylsuccinic acid derivatives.
