This paper presents a critical analysis of two transition state models for the bis-cinchona alkaloid catalyzed enantioselective dihydroxylation of olefms using a broad range of experimental data. In one model (Sharpless) the transition state resembles a metallaoxetane structure formed by [2 + 2] cycloaddition of Os=O and C=C, and in the other the transition state is a five-membered structure in which one axial and one equatorial oxygen of cinchona bound OsU4 are becoming attached to the olefmic carbons by a [3 + 2] cycloaddition process from an Os-olefin pi-complex (CCN model, Figure 1). Data on the enantioselectivity of the asymmetric dihydroxylation of a wide variety of olefmic substrates and on the selectivity of a range of catalyst structures agree well with expectations based on the CCN model, but not the Sharpless model.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. Synthetic Route of 4062-60-6, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 4062-60-6, in my other articles.

Promising test results on the biological activity of our previously described naphtho[1,2-d]oxazoles and heterobenz[1,2-d]oxazoles, obtained by the photochemical cyclization of 5-phenylethenyl- and 5-heteroarylethenyloxazoles, prompted us to continue with the photochemical synthesis of substituted naphtho[1,2-d]oxazoles, and to extend the photochemical cyclization to the synthesis of naphtho/heterobenz[2,1-d]oxazoles from 4-(aryl/heteroarylethenyl)oxazoles. The required p- and o-phenyl-substituted 5-arylethenyloxazoles were prepared from the corresponding alpha,beta-unsaturated aldehydes and the TosMIC reagent (tosylmethyl isocyanide) by the Van Leusen reaction. The substituted 4-(aryl/heteroarylethenyl)oxazoles were prepared by the Wittig reaction starting from various phosphonium salts and 2-H/methyl-4-oxazolecarbaldehydes.

An asymmetric intramolecular carbolithiation reaction was developed by combining the (-)-sparteine-mediated enantiotopos-differentiating deprotonation and the anionic 5-exo-trig cyclization. Achiral 6-phenylhex-5- enyl carbamates were efficiently cyclized furnishing regio-, diastereo- (dr >99:1), and enantioselectively (er >98:2) 1,2-trans-substituted cyclopentanes. The intermediate primary benzylic lithium-carbanion pairs were – in spite of their configurative lability – diastercoselectively substituted by versatile electrophiles creating a third consecutive stereogenic center. Additionally, some 4-functionalized 6-phenylhex-5-enyl carbamates were also cyclized in high yield to provide enantiomerically pure cyclopentanes incorporating three adjacent stereogenic centers.

A series of axially chiral 1-benzylidene-4-<4'-<(p-alkylphenyl>ethynyl>phenyl>cyclohexanes was prepared in racemic form and as optically active mixtures by application of the Hanessian olefination reaction.These compounds have two spectrally overlapping groups which leads to enhanced circular dichroism.And, with appropriate substituents, they form liquid crystal phases when heated above room temperature.The photochemical and material properties of these compounds were studied to assess their suitability for formation of a chiroptical liquid crystal switch.It was found that the Kuhn anisotropy factor (glambda) is too small for this application.

Most functionalizations of C-H bonds by main-group reagents occur at aryl or methyl groups. We describe a highly regioselective borylation of secondary benzylic C-H bonds catalyzed by an iridium precursor and 3,4,7,8-tetramethyl-1, 10-phenanthroline as the ligand. The reaction is directed to the benzylic position by a hydrosilyl substituent. This hydrosilyl directing group is readily deprotected or transformed to other functional groups after the borylation reaction, providing access to a diverse set of secondary benzylboronate esters by C-H borylation chemistry.

A reaction mechanism is the microscopic path by which reactants are transformed into products. Each step is an elementary reaction. In my other articles, you can also check out more blogs about 4062-60-6

Benzyltriphenylphosphonium tribromide (BTPTB), as a stable solid reagent, is easily prepared by the reaction of benzyltriphenylphosphonium bromide with Br2. This reagent can be used as an efficient reagent for the chemoselective oxidation of dialkyl and aryl-alkyl sulfides to their corresponding sulfoxides in the presence of diaryl sulfides and primary alcohols. All reactions were performed in a refluxing mixture of methanol and water in very short reaction times. Copyright Taylor & Francis Group, LLC.

Various (E)-hydroxystilbenes were synthesized from (E)/(Z) mixtures of methoxystilbenes through a new (Z)-(E) isomerization method followed by demethylation. The nematocidal activity appears when methoxystilbenes are demethylated to hydroxystilbenes. For this activity, a hydroxy group at the C-2 or C-3 position is necessary. Thus, 2-hydroxy-, 3-hydroxy-, 2,6-dihydroxy-, 3,4-dihydroxy-, 3,5-dihydroxy-, 2,2′-dihydroxy-, 3,3′-dihydroxy-, 3,4’dihydroxy-, 2-hydroxy-4-methoxy-, 5-hydroxy-2-methoxy-, 2-hydroxy-6-methoxy-, 6-allyloxy-2-hydroxy-, 3-hydroxy-5-methoxy-, and 5-allyloxy-3-hydroxystilbenes showed rather potent nematocidal activity. The activity of 5-allyloxy-3-hydroxystilbene was the strongest [minimal lethal concentration (MLC) = 30 muM]. The activities of the (E) and (Z) isomers were comparable. The activities were also retained, though they were weaker, in the dihydro derivatives, hydroxybibenzyls.
