The synthesis of versatile scaffold indolopyrans based on C-C radical-radical cross-coupling under metal-free conditions is described. The reaction involving single electron transfer between coupling partners followed by cage collapse allows highly selective cross-coupling while employing only equimolar amounts of coupling partners. Moreover, the mechanistic manifold was expanded for the functionalization of enamines to give the stereoselective synthesis of 2,3-dihydrofurans. This iodine-mediated oxidative coupling features mild conditions and fast reaction kinetics.

Despite numerous advances in spectroscopic methods through the latter part of the 20th century, the unequivocal structure determination of natural products can remain challenging, and inevitably, incorrect structures appear in the literature. Computational methods that allow the accurate prediction of NMR chemical shifts have emerged as a powerful addition to the toolbox of methods available for the structure determination of small organic molecules. Herein, we report the structure determination of a small, stereochemically rich natural product from Laurencia majuscula using the powerful combination of computational methods and total synthesis, along with the structure confirmation of notoryne, using the same approach. Additionally, we synthesized three further diastereomers of the L. majuscula enyne and have demonstrated that computations are able to distinguish each of the four synthetic diastereomers from the 32 possible diastereomers of the natural product. Key to the success of this work is to analyze the computational data to provide the greatest distinction between each diastereomer, by identifying chemical shifts that are most sensitive to changes in relative stereochemistry. The success of the computational methods in the structure determination of stereochemically rich, flexible organic molecules will allow all involved in structure determination to use these methods with confidence.

Highly sensitive and selective detection of nitro containing high energy organic compounds such as picric acid (PA), 2,4,6-trinitrotoluene (TNT) and 2,4-dinitrotoluene (DNT) has become a challenging task due to concerns over national security, criminal investigations and environment protections. Among various known detection methods, fluorescence sensors have gained special attention in recent time. The family of fluorescent sensors based on push-pull systems that incorporate nitrogen heterocycles as an electron-withdrawing group have a growing interest due to their high sensitivity, selectivity and easy tuning. The fluorescent sensors discussed in this review are classified and organized according to used azahetemcyclic scaffold, their functionality and their ability to detect of nitmaromatics by fluorescence quenching.

Through research, I have a further understanding and discovery of 4-Nitrobenzoic acid

Picolinamide group assisted sp(3) C-H bond oxidation of methylene groups to the corresponding carbonyl compounds has been achieved by using simple bottle ferrocene as catalyst and Cu(OAc)(2) or tert-butyl peroxybenzoate (TBPB) as oxidant under mild conditions. This method is applicable for picolinamide bound organic as well as organometallic compounds with yields in the range of 46-82%. Control experiments and mechanistic studies indicate that a radical mechanism is responsible for these oxidative transformations in which ferrocene acts as a catalyst.

(18R)-and (18S)-stereoisomers of resolvin E3 (RvE3), potent anti-inflammatory mediators, were synthesized stereo-and enantioselectively through the Wittig reaction of the carbonate of 6R,7R- and 6R,7S-dihydroxynona-2E, 4E-dienal, a C12-C20 part, with the phosphonium salt corresponding to the C1-C11 part. The stereoisomeric carbonate was prepared by the Swern oxidation of 3-(AcO)-6R, 7R-or 3-(AcO)6R, 7S-(dihydroxy-carbonate)-4-nonen-1-ol followed by the spontaneous elimination of the AcO group in one pot. The (6R, 7R)-(dihydroxy-carbonate)-alcohol for (18R)-RvE3 was, in turn, provided by stereoselective epoxidation of 9-(TBS-oxy) nona-4Z, 6E-dien-3R-ol with m-CPBA and the subsequent Pd-catalyzed addition of AcOH to the resulting syn vinyl epoxy alcohol followed by carbonate formation of the vic-syn-diol and TBS desilylation. The Mitsunobu inversion of the syn vinyl epoxy alcohol gave the anti isomer, which was converted to 3-(AcO)-6R, 7S-(dihydroxy-carbonate)-4-nonen-1-ol, the intermediate to (18S)-RvE3, by the same set of reactions.

A copper-mediated oxidative C-H/N-H annulation of aromatic amides with dialkyl malonates has been presented to afford synthetically valuable dihydrobenzoindoles and isoindolinones. The reaction proceeds through direct oxidative C(sp(2))H/C(sp(3))-H coupling followed by an intramolecular N-H/C(sp(3))-H dehydrogenative coupling to deliver the target motifs with broad scope and functional group tolerance.

The preparation of ORM-10921, a selective (2C)-adrenoceptor antagonist with promising anti-psychotic properties, was successfully achieved using asymmetric -alkylation of ,-unsaturated imide and Bischler-Napieralski cyclization/asymmetric reduction as the key steps. When the tetracyclic iminium 11S was used in the reduction, the diastereo-selectivity was poor, from which four stereoisomers of ORM-10921 were obtained, respectively. However, the diastereoselectivity could be significantly improved (with dr up to >97:3) when the tricyclic imine substrate 19S was applied in this reduction, suggesting an additional chelation from the side-chain methoxy group in the transition state. According to this protocol, ORM-10921 was accomplished in a highly enantioselective manner. In addition, two analogs 26Aa and 26Ba were prepared using this novel method, and the absolute configurations were unambiguously assigned by single crystal X-ray crystallography.
