A research note on the recalcitrance of carbon dioxide gas scrubbing compounds to biodegradation processes

A laboratory study was conducted to determine the feasibility of biotreatment of liquid Sulfinol waste stored at a gas treatment facility. Sulfinol is used to scrub impurities from gas generated from both traditional gas extraction and that from hydraulic fracturing processes. Chemical characterization and microbiological assessment showed that cultures of Sulfinol-degrading microorganisms could be enriched from Sulfinol-contaminated soil containing saturated concentrations of Sulfinol: a mixture of di-isopropanolamine (DiPA), sulfolane, and oxazolidone. Based on this initial finding from the enrichment culture study, batch reactors were incubated with inoculants from enrichment cultures containing known numbers of presumptive Sulfinol-degrading microorganisms. The microbial analyses of liquors from batch reactors showed microbial inhibition and/or loss of viability due to Sulfinol toxicity, even at the lowest Sufinol waste concentration used (5 percent of the original waste). The changes in concentrations of the chemicals in the batch reactor trials were a result of chemical rather than biodegradation processes. Further research is recommended to develop repeatable strategies for biodegrading the constituents of Sulfinol under field conditions.

Total synthesis of (-)-exiguolide

The first total synthesis of the naturally occurring enantiomer of exiguolide ((-)-1) has been completed. This very convergent synthesis features the following as main steps: (I) a Trost’s ruthenium-catalyzed ene-yne cross-coupling reaction (this complex transformation allows the challenging control of the C5-C28 double bond geometry along with the stereoselective construction of the tetrahydropyran ring A) and (II) a very efficient one-pot, two-step stereoselective conjugated allyllc alcohol substitution that allowed the control of the C15 stereogenic center.

Highly stereoselective samarium(II) iodide-mediated aldol reactions of acylaziridines with aldehydes

The samarium(II) iodide-mediated stereoselective aldol reactions of acylaziridines with aldehydes are described. beta-Amino-beta?-hydroxy ketones were synthesized in high yields by the aldol reaction of aldehydes with samarium enolates generated by aziridine-fragmentation of aziridinyl ketones with two moles of samarium(II) iodide. By the choice of an appropriate nitrogen protecting group, depending on the substituent at C-3 position of aziridinyl ketone, anti,anti-beta-amino-beta?-hydroxy ketones were diastereoselectively obtained among the four possible diastereomers. Further, enantiomerically pure anti,anti-beta-amino-beta?-hydroxy ketones were successfully obtained by this aldol reaction when chiral aziridinyl ketones were used. In addition, delta-amino-?-hydroxy-beta,gamma-unsaturated esters were also synthesized in high yields by the aldol reaction of aldehydes with samarium enolates generated by aziridine-fragmentation and olefin-migration of gamma,delta-aziridinyl-alpha,beta-unsaturated esters using two moles of samarium(II) iodide. This aldol reaction proceeded with complete alpha-regioselectivity and formed (E)-olefin selectively. By introducing chiral oxazolidin-2-one auxiliary to gamma,delta-aziridinyl-alpha,beta- unsaturated carbonyl system, this reaction was extended successfully to the asymmetric reaction and enantiomerically pure syn-delta-amino-beta?- hydroxy-beta,gamma-unsaturated esters were obtained in high yields.

Sequential hydroformylation/Diels-Alder processes: One-pot synthesis of polysubstituted cyclohexenes, cyclohexadienes, and phthalates from alkynes

A novel, one-pot hydroformylation/Diels-Alder sequence for the synthesis of multisubstituted cyclohexenes, cyclohexadienes, and phthalates has been developed. Various alkynes were efficiently converted into the corresponding products in good yields and with excellent diastereoselectivity through palladium-catalyzed hydroformylation followed by an AAD-type reaction (AAD: Amides-Aldehydes-Dienophiles). In view of the availability of the substrates, the atom-efficiency of the overall process, and the convenient introduction of substituents in the cyclohexene ring, this method complements current methods for the preparation of polysubstituted cyclohexane derivatives. Putting it together: A one-pot procedure for the diversity-oriented synthesis of multisubstituted cyclohexenes, cyclohexadienes, and phthalates through hydroformylation of alkynes followed by a Diels-Alder reaction has been developed (see scheme; EWG=electron-withdrawing group).

Recent advances in nucleophile-triggered CO2-incorporated cyclization leading to heterocycles

Carbon dioxide (CO2) has emerged as a sustainable, feasible, abundant one-carbon synthon and displays great potential in the synthesis of heterocycles such as lactones, lactams, and 2-oxazolidinones, which are privileged motifs in pharmaceutical chemistry demonstrating bioactivities. Although the fixation of CO2 is restricted due to its thermodynamic stability and kinetic inertness, multiple breakthroughs have been realized in annulation chemistry. This review concentrates on the advances made in the last five years in CO2-incorporated cyclization triggered by N-, O-, and C-nucleophiles. Three transformation modes of CO2 including carboxylative cyclization, carbonylative cyclization, and reductive cyclization have been summarized. Moreover, typical mechanisms and significant applications of these reactions are also described.
