Photooxidation of oxazolidine molecular switches: uncovering an intramolecular ionization facilitated cyclization process

Photooxidation of oxazoline (OXA) molecular switches through media-induced intramolecular ionization is reported. The formation of the photooxidation product occurs by attack of the flexible donor group (-CH2CH2OH) to the adjacent C=C with O-1(2) as the oxidant. The novel seven-membered ring sub-structure of the photooxidation product was inferred by HRMS, IR and H-1 NMR spectroscopy. Additionally, acid released from solvent photolysis was found to affect the product formation and efficiency of the photooxidation.

Chiral dirhodium catalysts derived from L-serine, L-threonine and L-cysteine: design, synthesis and application

A series of dirhodium tetrakis((4S)-3-(arylsulfonyl)oxazolidine-4-carboxylate), dirhodium tetrakis((4S,5R)-5-methyl-3-(arylsulfonyl)oxazolidine-4-carboxylate) and dirhodium tetrakis((4R)-3-(arylsulfonyl)thiazolidine-4-carboxylate 1,1-dioxide) complexes with different para-substituted arylsulfonyl groups (e.g. -NO2, -F, -CF3, -Me, -Bu-t, -OMe and -(C12H25)-C-n) derived from L-serine, L-threonine and L-cysteine, respectively, were prepared with yields in the range of 40-87% through refluxing ligands in water with Na4Rh2(CO3)(4). These chiral Rh(II) complexes have been fully characterized by EA, IR, UV-vis, NMR and specific rotation measurements. They are found to be effective chiral catalysts for asymmetric aziridination and cyclopropanation reactions in terms of reactivity and enantioselectivity. They are extremely stable and can be stored for a long period (at least 18 months) on the bench without adversely affecting their reactivity and selectivity. The heterocyclic rings as well as the substituents on the arylsulfonyl groups have critical effects on the degree of asymmetric induction. In general, a higher enantioselectivity was observed in the reactions catalyzed by the oxazolidine-4-carboxylate-derived catalysts than the thiazolidine-4-carboxylate 1,1-dioxide-based catalysts. Among these 21 new Rh(II) catalysts, the uses of dirhodium tetrakis((4S)3-((4-dodecylphenyl)sulfonyl)oxazolidine-4-carboxylate) (Rh-2(4S-DOSO)(4)) and dirhodium tetrakis-((4S,5R)-5-methyl-3-((4-nitrophenyl)sulfonyl)oxazolidine-4-carboxylate) (Rh-2(4S,5R-MNOSO)(4)) resulted in the highest levels of enantioselectivity in aziridination (94% ee) and cyclopropanation (98% ee) of styrene, respectively. The successful design and syntheses of these novel Rh(II) complexes enlarged the scope of accessible chiral dirhodium(II) catalysts.

Amelioration of Ischemia-Reperfusion Injury in an Isolated Rabbit Lung Model Using OXANOH

Objective: Acute respiratory distress syndrome (ARDS) remains a major cause of morbidity and mortality. Oxygen-free radicals (OFRs) produced during ischemia and reperfusion (IR) have been implicated as the final common pathway in the pathogenesis of this syndrome. Spin traps have been shown to decrease IR injury in several animal lung models. The hydroxylamine, OXANOH (2-ethyl-2,5,5-trimethyl-3-oxazolidine) has been proposed as an ideal spin trap that would trap extra- and intracellular OFRs producing the stable radical, OXANO(center dot) (2-ethyl-2,5,5-trimethyl-3-oxazolidinoxyl). Electron microscopy was used to investigate whether OXANOH would protect against IR injury in the rabbit lung. Methods: OXANOH was obtained by hydrogenation of its stable radical, OXANO(center dot) using a safe laboratory technique. Several doses of OXANOH were tested to identify a nontoxic dose. Two quantitative methods were used based on the average surface area of the alveoli and average number of alveoli per unit surface area using scanning electron microscopy (SEM). A total of 20 animals were subjected to 2 hours of ischemia followed by 4 hours of reperfusion. On reperfusion, the 4 groups (N = 5) received no treatment, OXANOH, superoxide dismutase (SOD)/catalase, or oxypurinol. Results: A therapeutic dose of 250 mu mol/L of OXANO(center dot) was suggested in this in vitro model. All the 3 treatments showed significantly less injury compared to the control group and that SOD/catalase was significantly different from OXANOH and oxypurinol (P < .008). Conclusion: OXANOH ameliorated IR injury in the isolated rabbit lung, almost as effectively as SOD/catalase and oxypurinol. A reaction mechanism is the microscopic path by which reactants are transformed into products. Each step is an elementary reaction.

Synthesis of cashew Mannich polyol via a three step continuous route and development of PU rigid foams with mechanical, thermal and fire studies

Renewable, biodegradable, agricultural resources are gaining increasing attention of many researchers because of growing environmental awareness and their potential to replace petrochemical derivatives. Cardanol obtained from cashew nut shell liquid (CNSL) is a renewable resource of immense potential. Cardanol, obtained as a byproduct of the cashew processing industry, is an important renewable resource and a unique phenolic compound carrying a 15-carbon side chain in the meta position, with varying degrees of unsaturation. The current research work describes the synthesis of new bio-based cashew Mannich polyols via the stepwise oxazolidine route and confirmed by spectral analysis. The foaming characteristics were studied and the polyols were successfully used in making rigid polyurethane (PU) foams with good mechanical, thermal and fire properties. The foams were characterized for density, flexural strength, morphology and limiting oxygen index (LOI) properties.

Development and Validation of High-glucoraphanin Broccoli F-1 Hybrids and Parental Lines

Sulforaphane is an anticarcinogenic isothiocyanate derived from 4-methylsulfinylbutyl glucosinolate (glucoraphanin), which is abundant in broccoli (Brassica oleracea var. italica) florets. However, some breakdown products from alkenyl glucosinolates present in many broccoli cultivars, particularly oxazolidine-2-thione hydrolyzed from 2-(R)-hydroxy-3-butenyl glucosinolate (progoitrin), have potentially harmful effects on human and animal health. The main objective of this study was to improve the glucoraphanin concentration in F-1 hybrids by cross-breeding with inbred lines and doubled haploids. Glucoraphanin concentrations in 31 of the 61 F-1 hybrids were significantly higher (P=0.05) than that of the commercial cultivar (Youxiu) with the highest concentration of glucoraphanin (4.18 mu mol.g(-1) dry weight) among eight reference cultivars. Sixteen of the F-1 hybrids had glucoraphanin concentrations 3-fold higher than that of ‘Youxiu’. Alkenyl glucosinolates were not detected in the new hybrids as a result of the parents having few of these compounds but were found in five reference cultivars. Most F-1 hybrids showed moderate indole glucosinolate concentrations and acceptable commercial traits. IL609 and IL702.2 were determined to be promising parental lines as a result of the high glucoraphanin concentration that they and their offspring contained. The findings also indicated that some F-1 hybrids do not show the high-glucoraphanin character of their parents; consequently, evaluation of these F-1 hybrids for their glucosinolate content is required for breeding high-glucoraphanin broccoli.
