    [Chemical reaction: See text] Both matched and mismatched diastereoselections have been observed in the aldol reactions of a range of chiral aldehydes with the dicyclohexylboron enolate of a chiral ethyl ketone related to L-erythrulose. As was previously observed in the

    Both matched and mismatched diastereoselections have been observed in aldol reactions of the B,B-dicyclohexylboron enolate of a protected l-erythrulose derivative with a range of chiral aldehydes. The stereochemical outcome of reactions with alpha-methyl aldehydes can be adequately explained within the

    The degradation of L-ascorbate (AsA) and its primary oxidation products, L-dehydroascorbate (DHA) and 2,3-L-diketogulonate (2, 3-DKG) were studied under physiological conditions. Analysis determined that L-erythrulose (ERU) and oxalate were the primary degradation products of ASA regardless of which compound was

    In the present work, we describe a new thiamine amperometric biosensor based on thiamine pyrophosphate (ThDP)-dependent transketolase (TK)-catalyzed reaction, followed by the oxidative trapping of TK intermediate α,β-dihydroxyethylthiamine diphosphate (DHEThDP) within the enzymatic active site.
