A series of 3-mercapto-propionic acid derivatives that function as reversible inhibitors of carboxypeptidase U have been prepared. We present a successful design strategy using cyclic, low basicity guanidine mimetics resulting in potent, selective an

Diastereometric esters of O-arylated (R)-lactic acids have been studied by 1 H NMR spectroscopy with respect to their potential application as reagents for chiral analysis. The substitution pattern of the acid moiety of the ester was found to have a

The methanolysis of (R)-styrene oxide catalyzed by SnCl4 has been found to proceed with complete regioselectivity with nucleophilic attack at the benzylic position, and with inversion of configuration at the benzylic carbon as the predominant stereoc

Molecular sieves have been shown to improve greatly the stereoselectivity in the palladium(II)-catalyzed reaction of cis-1,2-divinylcyclohene with chiral acids. Reactions run with molecular sieves and derivatives of (R)-lactic acids as nucleophiles a

La cyclisation oxydante de dienes-1,5 dans l'acide acetique en presence d'un systeme catalytique se regenerant a base de Pd(II)/Pd(OAc) 2 /MnO 2 /p-benzoquinone conduit, en fonction de la structure du diene-1,5, a des acetoxyexomethylenecyclopentanes

Molecular sieves have a decisive influence on the oxidative cyclisation of cis-1,2-divinylcyclohexane, resulting in enhanced diastereoselectivity (17–62%) as well as, occasionally, in opposite absolute configuration of the newly created chiral cent
