متن کاملAbsolute Stereochemistry of the Diepoxins
The exciton coupled CD method has been applied to determine the absolute configuration of the diepoxins, spiroketaI-linked naphthodiepoxydecaIinones of fungal origin. The CD spectra of the bis-dimethylaminobenzoate derivatives of the diepoxins 71, land ~c, reveal a positive chiral twist between the two substituted hydroxyl groups and thus infer the $ configuration at both of these stereogenic c...
متن کاملAbsolute stereochemistry of the strevertenes.
The CD exciton chirality method was applied to determine the absolute stereochemistry of the strevertenes, antifungal pentaene macrolides produced by Streptoverticillium sp. LL-30F848. The CD difference spectrum of strevertene A methyl ester 15-dimethylaminobenzoate showed a positive couplet between the dimethylaminobenzoate and the pentaene chromophores, and therefore established the 15R confi...
متن کاملThe absolute configuration of methylmalonyl coenzyme A and stereochemistry of the methymalonyl coenzyme A mutase reaction.
Rropionyl coenzyme A was carboxylated with epimerasefree carboxylase, and the resulting methylmalonyl coenzyme A (a) was reduced with Raney nickel. Isolation of (-)(R)-P-hydroxyisobutyric acid N-phenylcarbamate (11) from the reaction mixture showed that methylmalonyl coenzyme A (a) has the (S) configuration. Propionyl coenzyme A was also converted to deuteriosuccinate with a DrO extract of a be...
