The invention provides a method of preparing beta-d2 alkyl acid compounds. The method includes steps of: 1) performing a reduction reaction to a compound A with LiAlD4 to obtain a compound B; 2) performing -OD group protective reaction to the compound B to obtain an intermediate C; 3) performing a bromination reaction to the intermediate C to obtain a compound D; 4) under alkaline condition, performing a substitution reaction to the compound D and acetic acid to obtain the beta-d2 alkyl acid compounds. In the method, the alkyl acid, which is low in cost and is easy to obtain, is used as the initial raw material and is subjected to LiAlD4 reduction reaction, the -OD group protective reaction, the bromination reaction and the acetic acid substitution reaction to prepare the beta-d2 alkyl acid compounds. The method has simple process route and is free of expensive catalysts and the like during the reactions, is low in cost, and is high in total yield of the beta-d2 alkyl acid compounds. The method, when being amplified to gram-scale, has stable yield and good repeatability and is practicable and available.

SGLT2 inhibitors deuterated at sites susceptible to oxidative metabolism were found to have a slightly longer tmax and half-life (t 1/2), dose-dependent increase in urinary glucose excretion (UGE) in rats, and slightly superior effects on UGE in dogs while retaining similar in vitro inhibitory activities against hSGLT2. In particular, deuterated compound 41 has the potential to be a robust long-acting antidiabetic agent.

Isopenicillin N synthase (IPNS) is a non-heme iron(II) oxidase which catalyses the biosynthesis of isopenicillin N (IPN) from the tripeptide δ-l-α-aminoadipoyl-l-cysteinyl-d-valine (lld-ACV). Herein we report crystallographic studies to investigate the bi

α-Deuterium secondary kinetic isotope effects (KIEs) have been investigated for the reactions of anilines with benzyl, methyl and ethyl benzenesulfonates involving deuteriated aniline nucleophiles and substrates.The secondary KIEs observed are normal, kH/kD > 1.0, only for the deuteriated benzyl system and are of an inverse type, kH/kD N2 mechanism), in contrast to the reverse trend, i.e., the strain incurred by bond formation of the nucleophile is greater than the relief of steric congestion by bond breaking of the leaving group in the reactions of alkyl compounds (associative SN2 mechanism).The effects of substituents in the nucleophile (X) and leaving group (Z) on the secondary KIEs are in complete agreement with the transition-state variation predicted by the sign and magnitude of the cross-interaction constant, ρxz.
