Aldol condensation of biomass-derives coupled with hydrogenation is a promising route for the production renewable aviation fuel. In this study, bifunctional catalyst was prepared to integrate aldol cyclopentanone and hydroprocessing fuel in one pot. Due its strong mild-basic sites, Mg–Al–O performed best total yield dimer trimer 80.4%. Nickel screened out be favorable hydrogenation. Considerin...

A solid understanding of NMR spectroscopy is a basic learning goal for any student of chemistry. The hands-on approach to learning is the most powerful method for instructors in both classroom settings and in the teaching laboratory. Direct experience with acquiring and processing NMR spectra to determine product purity or to monitor the course of a chemical reaction is extremely valuable, espe...

SnoaL belongs to a family of small polyketide cyclases, which catalyse ring closure steps in the biosynthesis of polyketide antibiotics produced in Streptomyces. Several of these antibiotics are among the most used anti-cancer drugs currently in use. The crystal structure of SnoaL, involved in nogalamycin biosynthesis, with a bound product, has been determined to 1.35 A resolution. The fold of ...

The synthesis and characterization of some novel Pyrimidine derivatives have been presented. Acylation of resorcinol followed by nuclear prenylation with isoprene gives Chroman. Chroman on treatment with p-substituted benzaldehydes affords substituted chalcones. Pyrimidines have been prepared from chalcones by condensing with Guanidine hydrochloride in alkali medium. The structure of Pyrimidine...

Introduction Industrially condensation reactions are of great importance in the production of a number of key compounds. These include 2-ethyl hexanol, methyl isobutyl ketone (MIBK) and Guerbet alcohols. Over 1.5 million tonnes of these chemicals are produced worldwide every year using homogeneous bases such as NaOH and Ca(OH)2. It has been estimated for these compounds that 30% of the selling ...
