Background: The hetero-Diels-Alder (HDA) reaction is an important method for the construction of heterocyclic six-membered rings. The HDA reaction involving the carbonyl functionality as a dienophile or as a heterodiene makes dihydropyran ring accessible, which is present in many biologically active compounds. However, reactivity of the carbonyl group as a dienophile or as heterodiene is much less and for successf Read More

Background: Development of straightforward and atom/step-economic approaches for new C-C bond formation from readily available starting materials is one of the fundamental goals in the area of chemical synthesis. Among these strategies, Pd-catalyzed allylic alkylation represents one of the powerful synthetic tools and has been widely utilized in organic synthesis. The direct use of allylic alcohol itself instead of its deriv Read More

Background: To alleviate the crisis from depletion in non-renewable fossil reserves, catalytic conversion of the most abundant and renewable lignocellulosic biomass to biofuels and value-added chemicals has received much attention. In this respect, γ-valerolactone (GVL) derived from carbohydrates has gained considerable attention, as it can be further converted to biofuels and value-added chemicals via different cat Read More

Background: The preparation of hierarchical Y is of practical importance for industrial applications. Here, we utilized NaY or NH4Y as parent material to investigate its influence on catalytic performance of hierarchical Y prepared by post-treatment method. It was found that the hierarchical Y obtained by treating NaY exhibited superior catalytic performance than that by NH4Y in the benzylation of aromatics with Read More

Background: TiO2 is one of the most promising photocatalysts in photoelectrocatalytic (PEC) water splitting due to its high chemical stability, photocorrosion resistance, nontoxicity and low cost. One dimensional TiO2 nanowire arrays are expected to provide a large surface area and a direct electrical pathway for rapid photogenerated electron transport. However, the photocatalytic performances of TiO2 nanowire arra Read More

Background: The simply prepared and characterized alkaline starch (AS) by a new co-grinding protocol represents a superior catalytic activity in two- or three-component synthesis of hydroquinazolinones from either 2-aminobenzonitrile, 2-aminobenzamide, or isatoic anhydride. All AS-catalyzed reactions occur in higher yield and faster than the earlier methodologies. These performances are due to the several basic sit Read More
