Asymmetric synthesis of unusual amino acids: An efficient synthesis of optically pure isomers of beta-methylphenylalanine

Substitution of the diastereotopic beta-hydrogens of many alpha-amino acids provides an approach to the three dimensional topographic control of peptide structure. Asymmetric synthesis of the desired amino acids is needed to facilitate these studies. All four individual isomers of beta-methylphenylalanine, (2S,3S)-, (2R,3%)-, (2S,3R)- and (2R,3S)-beta-methylphenylalanine have been synthesized in high optical purity. The stereochemistry at the beta-center was set by the choice of starting material, either (+)- or (-)-3-phenylbutyric acid. These acids were attached to the appropriate D- or L-auxiliary (a 4-phenylmethyl-2-oxazolidinone) to give a 3′-phenylbutanoyl-4-phenylmethyl-2-oxazolidinone. Asymmetric bromination was accomplished via the chiral imide enolate bromination methodology of Evans and co-workers (J. Am. chem. Soc. 1990, 112, 4011-40). Evidence for asymmetric induction was obtained from the X-ray structure of one of the intermediate bromides. The bromide was converted to the diastereoisomeric azide by S(N)2 displacement using tetramethylguanidinium azide. After recovery of the chiral auxiliary by catalyzed hydrolysis, the chiral amino acid was obtained by catalytic hydrogenation over 10% Pd/C. All four isomers were obtained in enantiomeric purities of 95:5 to 99:1.

Stereoselective synthesis of unnatural (2S, 3S)-6-hydroxy-4-sphingenine-containing sphingolipids

6-Hydroxy-(4E)-sphingenine-containing sphingolipids are found in mammalian and bacterial membranes and have multiple intra- and intercellular functions. Most sphingolipids contain a (2S,3R)-2-amino-1,3-diol core structure, but only limited examples of unnatural (2S,3S)-2-amino-1,3-diol derivates have so far been reported. Using an underexplored hydrozirconation-transmetalation reaction and an unusual three-step-one-pot deprotection sequence, we were able to synthesize several unnatural (2S,3S)-6-hydroxy-(4E)-sphingenine-containing sphingolipids in only three (protected) or four (deprotected) consecutive steps, respectively, including a fluoresence-labeled derivative suitable for future biological studies.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data.

Optimization of benzoxazole-based inhibitors of Cryptosporidium parvum inosine 5?-monophosphate dehydrogenase

Cryptosporidium parvum is an enteric protozoan parasite that has emerged as a major cause of diarrhea, malnutrition, and gastroenteritis and poses a potential bioterrorism threat. C. parvum synthesizes guanine nucleotides from host adenosine in a streamlined pathway that relies on inosine 5?-monophosphate dehydrogenase (IMPDH). We have previously identified several parasite-selective C. parvum IMPDH (CpIMPDH) inhibitors by high-throughput screening. In this paper, we report the structure-activity relationship (SAR) for a series of benzoxazole derivatives with many compounds demonstrating CpIMPDH IC50 values in the nanomolar range and >500-fold selectivity over human IMPDH (hIMPDH). Unlike previously reported CpIMPDH inhibitors, these compounds are competitive inhibitors versus NAD +. The SAR study reveals that pyridine and other small heteroaromatic substituents are required at the 2-position of the benzoxazole for potent inhibitory activity. In addition, several other SAR conclusions are highlighted with regard to the benzoxazole and the amide portion of the inhibitor, including preferred stereochemistry. An X-ray crystal structure of a representative E¡¤IMP¡¤inhibitor complex is also presented. Overall, the secondary amine derivative 15a demonstrated excellent CpIMPDH inhibitory activity (IC 50 = 0.5 ¡À 0.1 nM) and moderate stability (t1/2 = 44 min) in mouse liver microsomes. Compound 73, the racemic version of 15a, also displayed superb antiparasitic activity in a Toxoplasma gondii strain that relies on CpIMPDH (EC50 = 20 ¡À 20 nM), and selectivity versus a wild-type T. gondii strain (200-fold). No toxicity was observed (LD 50 > 50 muM) against a panel of four mammalian cells lines.

Electrogenerated chiral 4-methoxy-2-oxazolidinones as diastereoselective amidoalkylation reagents for the synthesis of beta-amino alcohol precursors

A flexible and efficient synthesis of enantiomerically pure 4,5-substituted 2-oxazolidinones – important target molecules as precursors of pharmacologically active 2-oxazolidinones, beta-amino alcohols, beta-blockers and azasugar derivatives – is described. As starting materials, the enantiopure storage forms of chiral N-acyliminium ions (4RS,5S)-5-chloromethyl-4-methoxy-1,3-oxazolidin-2-one (2) and (4RS,5R)-4-methoxy-5-methyl-1,3-oxazolidin-2-one (3) were used; these are readily available from the chiral pool with the aid of electrochemical transformations. Substitution of the 4-methoxy group in building blocks 2 and 3 with a large variety of organometallic nucleophiles resulted in the trans-diastereoselective formation of enantiopure 4,5-disubstituted 2-oxazolidinones, with a high degree of flexibility in the substituent at the 4-position.
