Facile Routes for the Preparation of 3,4-Disubstituted 1,3-Oxazolidines and 1,2,5-Trisubstituted Imidazolidin-4-ones

Facile, alternative synthetic routes to (RS)-, (R)-, and (S)-3-benzyl-N-(2,6-dimethylphenyl)-1,3-oxazolidine-4-carboxamides (6), a chiral oxazolidine derivative of tocainide, are reported. The synthetic routes described herein also afforded (RS)-, (R)-, and (S)-11, which present the imidazolidin-4-one core and belong to a class of compounds interesting for their biological activities. All the final compounds and intermediates were fully characterized. Enantiomeric excesses of homochiral 6 and 11 were determined by capillary electrophoresis analysis using 2-hydroxypropyl-beta-cyclodextrin or highly sulfated gamma-cyclodextrin as chiral selectors.

Development of Asymmetric Reactions Using Chiral Oxazolidine-type Catalysts

A design of a chiral ligand and the metal-coordinated catalyst is very important for achievement of a highly enantioselective catalytic asymmetric reactions. Recently, we developed the chiral oxazolidine ligands having N,O-acetal structure, such as phosphinooxazolidine (POZ), phosphinooxazinane (POZI) and oxazolidine (OZ). POZ and POZI afforded products in an excellent enantioselectivities in Pd-catalyzed asymmetric allylic alkylation and tandem allylation. Furthermore, cationic Pd-POZ catalysts showed high levels of catalytic activity in the asymmetric Diels-Alder (DA) reactions of some dienes with oxazolidinone- or pyrrazolidinone-type dienophiles. Cationic Pd-POZ catalyst showed an excellent catalytic activity in the DA reaction in ionic liquid (IL). The catalyst could be reused eight times without significant decrease of yield and enantioselectivity in IL/CH2Cl2 solvent system. OZ ligand also worked as organocatalyst in the DA reaction of 1,2-dihydropyridies with acroleins to afford the useful intermediate of Oseltamivir.

Assessment of biocides and ultrasound treatment to avoid bacterial growth in diesel fuel

Prevention and avoiding growth of microorganisms inside fuel storage tanks is a major concern for the oil industry because the associated problems caused by corrosion, plugging and blockage in storage and dispensing facilities. To effectively control microbial growth in petroleum fractions, assessing new treatments and acquiring deepen knowledge about existing treatments must be performed. In the present work, we compare and evaluate the efficiency of several chemical and physical treatments on the growth of microorganisms found in real samples of diesel fuel from different storage tanks from petrol stations in Spain. The treatments include the use of ten organic biocides with different functional active groups, hydrogen peroxide and ultrasounds. The better results were obtained with water-soluble biocides, especially those with an oxazolidine group in the active compound, although the effectiveness of different biocides very much relies on biodiversity and physicochemical properties of the media.

Highly Stereoselective Palladium-Catalyzed [3+2] Cycloaddition of Vinyl Epoxides and N-Benzothiazolimines

An asymmetric [3+2] cycloaddition of racemic vinyl epoxides with N-benzothiazolimines has been presented under Pd-catalysis. This transformation provides rapid access to highly functionalized oxazolidine scaffolds in generally good yields along with high stereoselectivities (up to 99% ee, 8.5 : 1 d.r.) under mild conditions. The use of chiral BINAP ligand enabled this asymmetric transformation with a broad substrate tolerance.
