The hydroboration of representative heterocycles bearing an endocyclic double bond with diisopinocamphenylborane (Ipc2BH) was investigated systematically to establish the asymmetric induction achieved in the reaction.The hydroboration of 2,3- and 2,5-dihydrofurans, 1,4-epoxy-1,4-dihydronaphthalene, and 2,3-dihydrothiophene with Ipc2BH in THF at -25 deg C proceeded very cleanly to afford the corresponding trialkylboranes.These trialkylboranes readily eliminate alpha-piene on treatment with acetaldehyde to give the corresponding boronates, R*B(OR)2.Oxidation afforded in high yields the corresponding heterocyclic alcohols of 100percent ee.N-(Carbobenzyloxy)-3-pyrroline could not be hydroborated with Ipc2BH below 0 deg C.The oxidation of the intermediate trialkylborane gave N-(carbobenzyloxy)-3-pyrrolidinol in 89percent ee.Similarly, six-membered heterocyclic olefins, namely, 3,4-dihydropyran and 3,4-dihydrothiapyran, were hydroborated with Ipc2BH at 0 deg C in THF.The resulting trialkylboranes on treatment with acetaldehyde followed by oxidation yielded 3-hydroxytetrahydropyran and 3-hydroxytetrahydrothiapyran of 83percent and 66percent ee, respectively.N-(Carbobenzyloxy)-1,2,3,6-tetrahydropyridine, hydroborated with Ipc2BH at 0 deg C, followed by oxidation, afforded the corresponding 3- and 4-piperidinols in an 85:15 ratio.The asymmetric induction achieved during hydroboration was 70percent.The five-membered heterocyclic boronates of very high optical purity, highly versatile synthetic intermediates, were isolated both as the diethyl and the diethanolamine esters.

In a article，once mentioned of 383128-14-1

B(C6F5)3 has been found to be an effective catalyst for reduction of pyridines and other electron-deficient N-heteroarenes with hydrosilanes (or hydroboranes) and amines as the reducing reagents. The success of this development hinges upon the realization of a cascade process of dearomative hydrosilylation (or hydroboration) and transfer hydrogenation. The broad functional-group tolerance (e.g. ketone, ester, unactivated olefins, nitro, nitrile, heterocycles, etc.) implies high practical utility.

The discovery and synthesis of potential and novel antipsychotic coumarin derivatives, associated with potent dopamine D2, D3, and serotonin 5-HT1A and 5-HT2A receptor properties, are the focus of the present article. The most-promising derivative was 7-(4-(4-(6-fluorobenzo[d]isoxazol-3-yl)-piperidin-1-yl)butoxy) -4-methyl-8-chloro-2H-chromen-2-one (17m). This derivative possesses unique pharmacological features, including high affinity for dopamine D2 and D3 and serotonin 5-HT1A and 5-HT2A receptors. Moreover, it possesses low affinity for 5-HT2C and H1 receptors (to reduce the risk of obesity associated with chronic treatment) and hERG channels (to reduce the incidence of torsade des pointes). In animal models, compound 17m inhibited apomorphine-induced climbing behavior, MK-801-induced hyperactivity, and the conditioned avoidance response without observable catalepsy at the highest dose tested. Further, fewer preclinical adverse events were noted with 17m compared with risperidone in assays that measured prolactin secretion and weight gain. Acceptable pharmacokinetic properties were also noted with 17m. Taken together, 17m may constitute a novel class of drugs for the treatment of schizophrenia.

The key to shortening tuberculosis (TB) drug regimen lies in eliminating the reservoir of non-replicating persistent (NRP) Mycobacterium tuberculosis (Mtb). Pyrazinamide (PZA) is the only known drug used as part of a combination therapy that is believed to kill NRP Mtb and achieve sterilization. PZA is active only under low pH screening conditions. Screening and identification of NRP-active anti-TB compounds are severely limited because compounds are usually inactive under regular assay conditions. In an effort to design novel NRP-active anti-TB compounds, we used pyrazinamide as a core and hybridized it with the fragments derived from marketed drugs. One of these designs, compound 8, was a hybrid with fluoroquinolone. This compound exhibited >10 fold improvement in NRP activity under low pH condition as compared to pyrazinamide and a modest activity (0.8 log10 kill) under nutritionally starved NRP condition. Furthermore, compound 8 was active against fluoroquinolone-resistant strains and did not show any activity in a DNA supercoiling assay (gyrase inhibition), suggesting that its mechanism of action is not that of the parent fluoroquinolone. These results provide a novel avenue in the exploration of new chemotypes that are active against non-replicating Mtb.

Allylic oxidation of heteroatom substituted cyclic alkenes by tert-butyl hydroperoxide (70% TBHP in water) using catalytic dirhodium caprolactamate [Rh2(cap)4] forms enone products with a variety of 2-substituted cyclic enamides and 3,4-dihyro-2H-pyrans. These reactions occur under mild reaction conditions, are operationally convenient to execute, and are effective for product formation with as low as 0.25 mol% catalyst loading. With heteroatom stabilization of the intermediate allylic free radical two sites for oxidative product formation are possible, and the selectivity of the oxidative process varies with the heteroatom when R = H. Cyclic enamides produce 4-piperidones in good yields when R = alkyl or aryl, but oxidation of 2H-pyrans also gives alkyl cleavage products. Alternative catalysts for TBHP oxidations show comparable selectivities but give lower product yields.
