Enantiopure β3-neopentylglycine: synthesis and resolution
摘要:
A procedure has been developed for the large scale synthesis of enantiopure beta(3)-neopentylglycine and its Cbz-protected derivative. The synthetic route developed in Out laboratory features Cbz-protection of the racemic beta-amino acid followed by resolution with L-norephedrine and provides the enantiomerically Pure Cbz-beta-neopentylglycine in good yield and excellent enantiopurity. No toxic or dangerous chemicals are used, allowing the scale-up of this procedure without major safety concerns. (c) 2009 Elsevier Ltd. All rights reserved.

How can you use a ruthenium isomerization catalyst twice? A ruthenium-catalyzed sequence for the formal two-carbon scission of allyl groups to carboxylic acids has been developed. The reaction includes an initial isomerization step using commercially available ruthenium catalysts followed by in situ transformation of the complex to a metal-oxo species, which is capable of catalyzing subsequent oxidation

In our efforts to develop novel small-molecule inhibitors for the treatment of influenza, we utilized molecular modeling and the X-ray crystal structure of the PB2 subunit of the influenza polymerase to optimize a series of acyclic β-aminoacid inhibitors, highlighted by compound 4. Compound 4 showed good oral exposure in both rat and mouse. More importantly, it showed strong potency versus multiple

determination of the enantiomeric excess of various substrates. Herein, we show the versatility of the zinc tris(2‐pyridylmethyl)amine‐based stereodynamic probe by performing a detailed study of the imine formation process, by the extension of the sensing capabilities to other chiral compounds. A principal component analysis study of the system together with TD‐DFT studies highlights the molecular origin
