Towards functionalized silicon-containing alpha-amino acids: Asymmetric syntheses of sila analogs of homoserine and homomethionine

The homoserine and homomethionine sila analogs, (R)-HOSi(Me 2)CH2CH(NH2)CO2H ((R)-21) and (R)-MeSCH2Si(Me2)CH2CH(NH2)CO 2H ((R)-24), respectively, were each synthesized in nine steps and in 30 and 23% overall yield, respectively, from commercially available ClSiMe 2CH2Cl. The key step of both syntheses was the asymmetric alpha-bromination of an Evans amide to introduce the stereogenic center of the amino acids with defined absolute configuration. While the preparation of the homomethionine analog (R)-24 followed the expected pathway, the sila analog of homoserine, (R)-21, was unexpectedly formed during the catalytic hydrogenation of an N3CH2-substituted silane derivative.

Chemical fixation of CO2 to allylic (alpha-Allenylic) amines: A green route to synthesis of functionalized 2-Oxazolidones

2-Oxazolidones are an important class of nitrogen-containing heterocyclic compounds, which have been found to have a wide range of applications as chiral auxiliaries and chemical intermediates in organic synthesis. Moreover, some 2-oxazolidones such as linezolid, toloxatone, and tedizolidare are shown to have high potency as biologically active molecules and are widely used in the pharmaceutical industry. Therefore, many efforts have been dedicated to synthesize these useful cores. Among recent reported synthetic methods, the carboxylative cyclization reactions of inexpensive and easily available allylic and 2,3-allenic amines with CO2 are one of the most interesting and promising synthetic procedures from the viewpoint of developing CO2 as carbon source, since the chemical conversion of CO2 into the value-added chemicals is one of the most important topics in green and sustainable chemistry. In this mini review, we highlight the advances in the synthesis of 2-oxazolidone derivatives through chemical fixation of CO2 to allylic and 2,3-allenic amines from 1987 to 2017, with special emphasis on the mechanistic aspects of the reactions.

Samarium diiodide as an efficient catalyst for the conversion of N-acyloxazolidinones into esters

The transformation of N-acyloxazolidinones into esters is readily performed using catalytic amounts of samarium diiodide in tetrahydrofuran at room temperature. This method allows the isolation of various esters without racemization in the case of scalemic substrates and the recovery of oxazolidinones in good yields. Georg Thieme Verlag Stuttgart.

Process for preparing Ezetimibe intermediate by enantioselective CBS catalyzed ketone reduction with BH3-DEA prepared in situ

The (S) alcohol in the benzylic position of compound 2, a key intermediate in the synthesis of the cholesterol lowering agent Ezetimibe, was introduced by the (R)-MeCBS catalyzed asymmetric carbonyl reduction of ketone 1 using borane diethylaniline complex (BDEA) as the reducing agent. The latter was prepared in situ from sodium borohydride (NaBH4), diethylaniline (DEA) and dimethylsulfate (DMSO4). BDEA prepared in situ offers considerable advantages from the industrialization standpoint (cost and stability on storage of the reagents) over commercial solutions of BH3-THF (BTHF) or BH3-DMS (BMS). The effect of critical reaction parameters such as addition mode of reagent, temperature, solvent, reaction quenching as well as LiCl addition on the selectivity has been examined. This reaction has been successfully applied in the process for the preparation of key intermediate 2 for Ezetimibe.

Absolute configuration of lactams and oxazolidinones using kinetic resolution catalysts

A simple method for determining the absolute configuration of oxazolidinones, lactams, and their derivatives using kinetic resolution catalysts is described. The optically pure substrates were acylated using the (S)-HBTM and the (R)-HBTM catalyst, and the faster reaction was determined. An empirical mnemonic was developed for the assignment of the absolute configuration based on the fast-reacting catalyst.

Novel 3-chlorooxazolidin-2-ones as antimicrobial agents

Antimicrobial resistance against many known therapeutics is on the rise. We examined derivatives of 3-chlorooxazolidin-2-one 1a (X = H) as antibacterial and antifungal agents. The key findings were that the activity and apparent in vitro cytotoxicity could be controlled by the substitution of charged solubilizers at the 4- and 5- positions. These changes both significantly increase the antifungal potency and decrease cytotoxicity. Particularly effective were trialkylammonium groups which led to 400- to 600-fold increases in the antifungal therapeutic index when compared to their unsubstituted counterparts.
