Two novel soluble polymer-bound oligo-L-leucines 2 and 5, Which can be retained by a membrane reactor system, have been prepared and used as catalysts for the continuously operated asymmetric epoxidation of chalcone. The optimized batch reaction conditions yield epoxychalcone in high enantioselectivities (up to 94%) and conversions (over 99%) after 15 minutes.

The hydantoinase process was shown to be extendable to the production of highly lipophilic, silicon-containing amino acids. Two hydantoinases of different origin and stereoselectivities and one L-N-carbamoylase were used for the highly stereoselective bioconversion of (dimethyl)phenylsilyl- and 1-methyl-1-silacyclopentyl substituted alanine derivatives. The enantiomeric purities and absolute configuration of the products were determined with reference compounds that were synthesized with the aid of the Evans oxazolidinone auxiliary.

In an article，Which mentioned a new discovery about 102029-44-7

In an effort to find answers to the tantalizing questions about the absolute configurations of a group of long-known natural phenylpropanoids with very similar structures but different signs for the optical rotations, the compounds in question were synthesized in enantiomerically pure form using Evans asymmetric alkylation to generate the stereogenic centres with predefined absolute configurations. The 1H and 13C NMR spectra of the synthetic products were very consistent with those reported for their natural counterparts. In most cases, the optical rotations were also consistent with the corresponding data for the natural samples. The new findings not only allowed unequivocal assignments of the absolute configurations for the natural products, but also revealed that the configurations of closely related compounds from the same plant may be different.

The second total synthesis of macrocidin A afforded the bioherbicidal fungal metabolite in 16 steps starting from doubly protected l-tyrosine. The 3-octanoyl side chain with the alpha-methyl group and an omega-bromo epoxide already in place was attached to the tetramic acid via a Yoshii-Yoda acylation, and the macrocycle was eventually closed in 55% yield by a Williamson etherification between the phenolate and the epoxy bromide.

Sequential carbophilic addition of organolithium reagents and N-acyliminium ion cyclization of N-phenethylimides 1 affords the substituted isoquinolones 3 in high yields, with the possibility of varying the substituent at the C-1 position of the isoquinoline ring by changing the organolithium reagent. Ready access to the isoquinoline nucleus via Parham-type cyclization of imides 2 is also described. We have shown that iodinated imides 2 tolerate the metal-halogen exchange in the presence of the imide group, and the intramolecular cyclization of the so-obtained aromatic organometallic derivatives leads to the corresponding enamides 4. Both approaches have allowed the efficient preparation of various types of the isoquinoline class of alkaloids, just by changing the substitution pattern on the readily available starting imides. Thus, we have developed convenient alternative routes for the synthesis of benzo[a]quinolizidones and their 2-oxa analogs, isoindoloisoquinolones, dibenzo[a,h]quinolizidones, and thiazolo- and oxazolo[4,3-a]isoquinolones.

The answer is in thermodynamics and kinetics.In a document type is Article, and a compound is mentioned, 16251-45-9, (4S,5R)-4-Methyl-5-phenyloxazolidin-2-one, introducing its new discovery.

alpha-N-Acylamino acids have been developed as useful reagents for the preparation of optically pure alpha-aminoalkylaryl ketones.Protection of the amino group as either the ethoxycarbonyl or benzenesulfonyl derivative allows alanine to serve as an effective educt for the chirally specific synthesis of a variety of structures containing the phenylethylamine backbone.Benzene undergoes Friedel-Crafts acylation with the N-acylalanine acid chloride.Catalyst complexation with oxagenated aromatics, however, prohibits acylation of aryl ethers.An arylmetallo reaction scheme overcomes this problem and also affords regiospecificity not attainable in conventional acylations.As examples, optically pure ephedrines and amphetamines were directly synthesized without recourse to resolution since the chirality of the amino acid educt was entirely conserved throughout the process.
