Preliminary synthetic studies of methyllycaconitine, a potent nicotinic acetylcholine receptor antagonist: Rapid syntheses of AE-Bicyclic analogues

A series of bicyclic analogues incorporating the homocholine motif of methyllycaconitine has been prepared to test the hypothesis that this is the essential pharmacophore of this potent, selective nicotinic receptor antagonist. A double Mannich reaction has been employed to construct the 3-azabicyclo[3.3.1]-nonane ring system, containing an N-ethylpiperidine moiety. The neopentyl-like alcohol was then esterified, using isatoic anhydride under basic conditions, to afford the corresponding anthranilate.

Cationic rhodium(I)/H8-binap complex catalyzed [2+2+2] cycloadditions of 1,6- And 1,7-diynes with carbonyl compounds

We have established that a cationic rhodium(I)/H8-binap complex catalyzes [2+2+2] cycloadditions of a variety of 1,6and 1,7-diynes with both electron-deficient and electron-rich carbonyl compounds, leading to dienones in high yield under mild reaction conditions. In the reactions with acyl phosphonates, the reactivity of 1,6- and 1,7-diynes was highly dependent on their own structures. The addition of chelating diethyl oxalate effectively promoted the [2+2+2] cycloadditions involving acyl phosphonates, presumably due to the equilibrium formation of the desired 1:1 rhodium complex of the diyne and the acyl phosphonate by facile ligand exchange between the diyne and weakly coordinated diethyl oxalate. In the reactions involving bifunctional carbonyl compounds or unsymmetrical 1,6-diynes, high chemo- or regioselectivities were observed. Wiley-VCH Verlag GmbH & Co. KGaA.

Hydroboration. 71. Hydroboration of Representative Heterocyclic Olefins with Borane-Methyl Sulfide, 9-Borabicyclo<3.3.1>nonane, Dicyclohexylborane, and Disiamylborane. Synthesis of Heterocyclic Alcohols

The hydroboration of representative heterocycles bearing an endocyclic double bond with borane-methyl sulfide (BMS), 9-borabicyclo<3.3.1>nonane (9-BBN), dicyclohexylborane (Chx2BH), and disiamylborane (Sia2BH) was investigated systematically to establish the optimum conditions for the clean and quantitative hydroboration.The hydroboration of 2,3- and 2,5-dihydrofurans with BMS (3:1 molar ratio) at 25 deg C for 1 h affords the trialkylborane, readily oxidized to 3-hydroxytetrahydrofuran in excellent yield.However, preparation of the corresponding dialkylboranes from these olefins using 2 olefin/BMS was not possible even at 0 deg C.Excess hydride and prolongated reaction time cause ring cleavage of the alkylboranes to yield both unsaturated alcohol and the dihydroborated products 1,3- and 1,4-pentanediols.Hydroboration of both 2,3-dihydrothiophene and 2-methyl-4,5-dihydrofuran with BMS proceeds cleanly to the trialkylborane stage, oxidized to the corresponding alcohols in almost quantitative yields.Hydroboration of 3-pyrroline with BMS could not be achieved with the unprotected nitrogen atom.Such hydroboration could be accomplished by protecting the nitrogen atom with the benzyloxycarbonyl group affording the trialkylborane, readily converted to N-(benzyloxycarbonyl)-3-pyrrolidinol in good yield.Conditions for a clean hydroboration of these heterocyclic five-membered olefins with 9-BBN, Chx2BH, and Sia2BH were also established.In all cases clean trialkylboranes were obtained, readily oxidized to heterocyclic alcohols in high yields. 3,4-Dihydropyran, on hydroboration with BMS, followed by oxidation, affords 3-hydroxytetrahydropyran in good yield.However, ring cleavage in this case is greater when compared to 2,3-dihydrofuran. 2-Methoxy- or 2-ethoxy-3,4-dihydro-2H-pyran readily undergo hydroboration with BMS to the trialkylboranes, oxidized to the corresponding trans and cis alcohols in a 7:3 ratio.As the steric requirements of the dialkylborane are increased, more trans alcohol is formed.Thus at 0 deg C, the ratios of trans to cis alcohols were increased from 1:1 to 7:3 and then to 8:2 with 9-BBN, Chx2BH, and Sia2BH, respectively.N-(Benzyloxycarbonyl)-1,2,3,6-tetrahydropyridine is readily hydroborated with BMS, 9-BBN, Chx2BH, and Sia2BH to the corresponding trialkylboranes, readily oxidized to N-(benzyloxycarbonyl)-3- and -4-piperidinols in good yield.Strongly basic groups in the heterocyclic ring can greatly reduce the ease of hydroboration, and the introduction of boron beta to the heteroatom can lead to elimination.However, both problems can be avoided to provide ready hydroboration-oxidation of heterocyclic olefins.

Observations on the reactivity of thiyl radicals derived from 3,6-epidithiodiketopiperazine-2,5-diones and related congeners

A range of thiyl radicals derived from the reduced form of epidithiodiketopiperazines (ETPs) act as polarity reversal catalysts for the hydrosilylation of an enol lactone but not for H-atom abstraction from a model ribose ester.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Product Details of 57203-01-7, you can also check out more blogs about57203-01-7

Formation and application of electrochemically active cross-linked triarylamine-siloxane films using the Piers-Rubinsztajn reaction

Cross-linked triarylamine-siloxane hybrid thin film have been formed using Piers-Rubinsztajn chemistry. Key to this approach was the use of a ring-opening reaction to prevent the evolution of volatile small molecules. A representative cyclic ether containing biphenyl triarylamine compound was synthesized and on ring-opening was shown to form a smooth, glassy, and electroactive films by cross-linking with tetrakis(dimethylsiloxy)silane (QM?4). It was found that the films were electrochemically active with low glass transition temperatures. Cross-linked films were incorporated into organic light emitting diodes (OLEDs) under various conditions and functionality within OLEDs was confirmed. Finally, the resistance of the system to dissolution (orthogonality) was considered by casting F8T2, a p-type emitting polymer, from solution on top of the cross-linked film, which formed a working OLED.
