Palladium-catalyzed oxamidation of alkenes: A new approach to benzoxazolidines

A novel palladium catalyzed protocol for the synthesis of benzoxazolidine by the reaction sulfamido-phenol and terminal alkene was developed. This oxamidation process is simple and does not require any ligand, base or inert atmosphere for the overall transformation. From control experiments, it is apparent that the cross-coupling reaction proceeds with initial formation of enesulfonamide which undergoes nucleopalladation by the intramolecular annulation and subsequent protodepalladation by TsOH to afford the benzoxazolidine.

Synthesis of Enantiopure trans-2,5-Disubstituted Trifluoromethylpyrrolidines and (2S,5R)-5-Trifluoromethylproline

Enantiopure trans-2,5-disubstituted trifluoromethylpyrrolidines were prepared on a several gram scale starting from a readily available chiral fluorinated oxazolidine (Fox). A pure oxazolopyrrolidine intermediate could be obtained after an efficient separation by selective diastereomer destruction. The addition of various Grignard reagents on this oxazolopyrrolidine provided disubstituted pyrrolidines with moderate to complete trans diastereoselectivity. The highly valuable compound (2S,5R)-5-trifluoromethylproline could be synthesized from the same oxazolopyrrolidine intermediate via a Strecker-type reaction.

Asymmetric synthesis of both (R)- and (S)-arundic acid

The asymmetric synthesis of both (R)- and (S)-arundic acid has been achieved via the key step of a stereoselective alkylation reaction using non-cross-linked polystyrene (NCPS) supported (4R)- and (4S)-2-phenylimino-2-oxazolidine as chiral auxiliaries. This method is efficient (both enantiomers were obtained in 99% ee and 60% overall yield) and the chiral auxiliaries can be recovered quantitatively by simple filtration.

Simple Oxazolidine Chiral Diene Ligands for Enantioselective Rh-Catalyzed Conjugate Additions

Simple oxazolidine-based chiral diene ligands, ultimately derived from serine, have been synthesized using the Seebach self-regeneration of stereocenters strategy. The ligands have been used in the enantioselective Rh-catalyzed conjugate addition of aryl boronic acids to cyclohexenone. An efficient ‘in vacuo’ reaction protocol has been developed as part of this study.

Effect of Ionic-Strength and pH Value in Mobile Phase on Enantio-Separation of BSA High Performance Liquid Chromatography Column

BSA chiral columns were prepared based on column modification method with carbonyl imidazole as cross-linker. Enantioseparation of tryptophan, pidotimod and 4-phenyl-1,3-oxazolidine-2-thione (L-ben) was obtained on the BSA chiral column by HPLC. The effects of pH values and ionic strength of mobile phase on enantioseparation performance were investigated. For L-tryptophan, the retention factor (k’) increased significantly as the pH value increased from 5.0 to 7.0. While for D-tryptophan k’ rarely changed and the resolution factor (R-s) increased from 1.15 to 8.91. In contrast, the retention factor (k’) for RS- and SR-pidotimod decreased as the pH value increased from 5.0 to 7.0. For L-ben, k’ was only a slight increase when the pH value increased. The retention factors of three enantiomers fluctuated as ionic strength increased. However, Rs decreased when a buffer concentration increased.

Substituted chromones in [3+2] cycloadditions with nonstabilized azomethine ylides: synthesis of 1-benzopyrano[2,3-c]pyrrolidines and 1-benzopyrano[2,3-c:3,4-c ‘]dipyrrolidines

Chromones bearing electron-withdrawing substituents at the 2- or 3-position react with nonstabilized azomethine ylides to produce 1-benzopyrano[2,3-c]pyrrolidines in good yields. Reactions of 3cyanochromones proceed diastereoselectively to give 1-benzopyrano[2,3-c]pyrrolidines and tetrahydro-1H-spiro[chromeno[2,3-c]pyrrol-9,5′-oxazolidine]-9a-carbonitriles, depending on the reactant ratio, as a result of a 1,3-dipolar cycloaddition of the azomethine ylide at the double bond and carbonyl group of the chromone system. The latter undergoes demethylenation and recyclization into a novel hexahydrochromeno[2,3-c:3,4-c’]dipyrrole tetracyclic system on heating with hydrochloric acid. (C) 2014 Elsevier Ltd.

Oxazolidine Formation, or Loss of Acid, from Attempted Fluorination of Amide Side-Chain in 2-Nitroimidazoles

Reaction of Etanidazole (a 2-nitroimidazole derivative with an amide side-chain containing a hydroxyethyl group) with triflic anhydride gives, depending on conditions, a trifluoromethyl(sulfonyl)oxazolidine via a cyclization reaction, or a fluorine-free formate derivative; reaction with tosyl chloride gives only a chloroethyl derivative. An attempt to replace a Br-atom in a related propyl-containing amide side-chain by a F-atom forms instead a propylene derivative via loss of HBr. The studies stem from interest in use of 2-nitroimidazoles with fluorine-containing amide side-chains as hypoxia markers.

QSAR Studies on Some of Dichloroacetyl Oxazolidine Herbicide Safeners

In order to find activity of herbicide safener, The MM+ and Polak-Ribiere algorithm were employed to calculate the properties of dichloroacetyl oxazolidine compounds. The QSAR equation of this series compounds was obtained by using (Least-Squares Regression) PLS regression. The results showed that log p and dipole moment played a major role, variable surface area (aprox), hydration energy, refractivity and polarizability played a secondary role. The equation building of this series compounds can not only forecast the activity of new compound, but also lead design of higher activity herbicide safener.

Three-Component Reactions of Diazoesters, Aldehydes, and Imines Using a Dual Catalytic System Consisting of a Rhodium(II) Complex and a Lewis Acid

A dual catalytic system, dirhodium tetrapivalate/ytterbium(III) triflate, enables the three-component reactions of alpha-alkyl-alpha-diazoesters, aromatic aldehydes, and N-benzylidenebenzylamine derivatives to afford the corresponding beta-amino alcohols in good yields after hydrolysis of the oxazolidine cydoadducts, whereas no beta-amino alcohols are obtained in the absence of ytterbium(III) triflate. A similar dual catalytic system, dirhodium tetraacetate/ytterbium(III) triflate, is found to be effective in accelerating the reactions of alpha-aryl-alpha-diazoesters in high yields. Furthermore, the reactions using dimethyl diazomalonate are described.
