New Approaches to Branched β-Amino α-Hydroxy Acids, Taxol Side-chain Analogs

The aqueous layer was extracted with diethyl ether and the combined organic phase was washed with brine and dried over MgSO 4. The solvent was removed under reduced pressure,

The diastereomeric excess (de) of all metal com- plexes was determined by chiral HPLC analysis of the amino acids isolated by use of the ion-exchange method from the acid

The combined extracts were dried (MgSO 4 ) and concentrated under reduced pressure to furnish a color- less oil which was purified by flash chromatography on silica (4 g, column 4 cm

With the ready availability of isoxazolines, built from alkenes and nitrile oxides, and with the rich chemistry and manifold transformations to acyclic structures in mind,

Several compounds were found to be effective against growth of fungi, and O- myristoyl-dl-serine 2 and N-phenylacetyl-threo-dl-phenylserine 8 completely inhibited the growth of

The contribution of this paper is to apply Rosa’s (2013) social acceleration theory to the specific con- text of logistics warehousing and to demonstrate how speeding up order

Thus, the influx of BCAA leads to a rapidly higher expression of the amino acid transporter CD98hc (Yan and Lamb, 2010) supporting the inflammatory response of intestinal

The preceding reasoning leads me to conclude that for i = 1,..., n , the w i ′ income is the lowest possible level of income which guarantees, first, that the relative
