Tandem radical cyclizations promoted by O-stannyl ketyls

This work summarizes an investigation of tandem radical cyclizations triggered by O-stannyl ketyls. This organometallic reactive intermediate is prepared from the reaction of tributyltin hydride (nBu3SnH) with a carbonyl functional group by a free radical chain mechanism. Several precursor substrates leading to ‘separated’, ‘spiro’, and ‘fused’ cyclopentanoid ring systems were investigated which collectively have good synthetic potential for the construction of a wide array of substituted polycyclic products.

I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 4062-60-6, help many people in the next few years.Formula: C10H24N2

Crown ether catalyzed stereospecific synthesis of Z- and E-stilbenes by Wittig reaction in a solid-liquid two-phases system

Potassium hydroxide and a catalytic amount of 18-crown-6 are used, in alternative to the classical Wittig conditions, to prepare very rapidly and stereoselectively Z- and E-stilbenes. In particular, the use of benzyltriphenylphosphonium iodides always leads to a complete Z- stereospecificity, while benzyldiphenylchlorophosphonium salts give a complete E-stereospecificity.

Mn(OAc)3-promoted sulfur-directed addition of an active methylene compound to alkenes

Various alkenes substituted at the 1,2-positions by phenyl, thiophene and furan rings were reacted with 3-(4-methoxyphenyl)-3-oxopropanenitrile in the presence of Mn(OAc)3¡¤2H2O. The exact structure and configuration of the dihydrofuran derivatives formed were determined. In all cases only one regioisomer was formed. The observed regioselectivity was explained on the basis of the formation of a complex between Mn(OAc) 3, alkene, and 3-(4-methoxyphenyl)-3-oxopropanenitrile, which directs the mode of the addition to the double bond.

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.Related Products of 4062-60-6, you can also check out more blogs about4062-60-6

Mechanistic studies on au(I)-catalyzed [3,3]-sigmatropic rearrangements using cyclopropane probes

A comparative study of the Au(I)-catalyzed [3,3]-sigmatropic rearrangement of propargylic esters and propargyl vinyl ethers is described. Stereochemically defined cyclopropanes are employed as mechanistic probes to provide new synthetic and theoretical data concerning the reversibility of this type of rearrangement. Factors controlling the structure-reactivity relationship of Au(I)-coordinated allenes have been examined, therebyallowing for controlled access to orthogonal reactivity.

Sulfinyl group as an intramolecular nucleophile: Synthesis of bromohydrins from beta-methyl-gamma,delta-unsaturated sulfoxides with high 1,2-asymmetric induction

Bromohydrins have been prepared from beta-methyl-gamma,delta-unsaturated sulfoxides with high regio- and stereoselectivity. The reaction proceeds via neighboring group participation of the sulfinyl moiety with inversion of sulfoxide configuration as proven by an 18O labeling study and x-ray crystallography.

Synthesis and inotropic activity of 1-(O-aminoalkyloximes) of perhydroindene derivatives as simplified digitalis-like compounds acting on the Na+,K+-ATpase

A series of 5-substituted (3aS,7aR)-7a-methylperhydroinden-3a-o1 derivatives bearing a 1(S)-(omega-aminoalkoxy)iminoalkyl or -alkenyl substituent was synthesized, starting from the Hajos-Parrish ketol 47, as simplified analogues of very potent 17beta-aminoalkyloximes with digitalis skeleton, previously reported. The target compounds were evaluated in vitro for displacement of the specific [3H]ouabain binding from the dog kidney Na+,K+-ATPase receptor. Some of them revealed IC50 values in the micromolar range. The most active compounds possess a cyclohexyl group in the 5(S) position and in position 1(S) the same aminoalkyloxime groups already reported for the digitoxigenin-like series in position 17beta. Although the ring conformation of these derivatives was comparable to that of uzarigenin, the binding affinities of the most active ones were 4/8-fold lower in comparison to that standard. Three compounds among those with the highest affinities were assayed in vitro for their inotropic activity on an electrically driven guinea pig left atrium and were found to be less potent than both digoxin, the most widely used inotropic agent, and the corresponding digitalis 17beta-aminoalkyloximes.

Discovery of [(3-bromo-7-cyano-2-naphthyl)(difluoro)methyl]phosphonic acid, a potent and orally active small molecule PTP1B inhibitor

A series of quinoline/naphthalene-difluoromethylphosphonates were prepared and were found to be potent PTP1B inhibitors. Most of these compounds bearing polar functionalities or large lipophilic residues did not show appreciable oral bioavailability in rodents while small and less polar analogs displayed moderate to good oral bioavailability. The title compound was found to have the best overall potency and pharmacokinetic profile and was found to be efficacious in animal models of diabetes and cancer.
