This review concerns the role of microwave irradiation in the synthesis of heterocycles starting from carbohydrates. This topic has received increasing interest owing to the wide variety of heterocyclic compounds as biologically significant chiral natural products or drugs, and products for industrial application, which cover nearly all aspects of carbohydrate chemistry. In particular, the possibility of employing microwave irra Read More

In this article we present (+)-3-carene as a valuable source for the synthesis of compounds with various odoriferous properties. Described compounds consist of carane, bicyclo[3.1.0]hexane, and gem-dimethylcyclohexane system in their structure. Olfactory comparative analysis with regard to the structure has been discussed. Fragrance of molecules varies from different fruit notes to floral and woody. Future prospect Read More

The radical TEMPO (2,2,6,6-tetramethylpiperidine 1-oxyl radical) and its derivatives are well-established catalysts for oxidation processes, and now used extensively in organic synthesis and industrial applications as a mild, safe, and economical alternative to heavy metal reagents as highly selective oxidation catalysts. In this review, we attempt to fully review the recent advances in the syntheses of TEMPO and its derivative Read More

Porphyrin is a kind of versatile chemically sensitive materials for application in chemical sensors. Recently, a variety of porphyrinic polymer membranes have been developed as gas sensors. Most of them are based on the photoluminescent or photoexcited state quenching of porphyrin dyes. Many porphyrinic gas sensors are composed of porphyrin or its derivatives immobilized on gas permeable polymer membranes. In Read More

Attempts to induce stereoselectivity in the conjugate addition to the α,β-unsaturated acceptors have been investigated by numerous research groups, classically through the use of either a chiral acceptor or chiral donor component in the reaction. The asymmetric Michael addition catalyzed by chiral catalysts has been extensively proven and established to be a powerful synthetic tool for especially a range of asym Read More

The reaction of a series of symmetric and unsymmetric triaminobenzene derivatives with proton as electrophile has been studied. The formation of both Wheland complex (C-H salt) and N-H salt in relative amount depending on the experimental conditions has been observed. In the case of the attack of the proton on the nitrogen atom, the 1H and 13C NMR spectra showed the equivalence of three aromatic protons (and related Read More
