Synthesis of enantiopure aminocyclopropanes by diastereoselective addition of a chiral amino substituted organozinc carbenoid to alkenes

The synthesis of enantiopure aminocyclopropanes is reported, via direct aminocyclopropanation of alkenes with a zinc carbenoid containing a chiral auxiliary. The methodology was applied to the synthesis of a protected aminocyclopropane present in the immunosuppressant Belactosin A. Georg Thieme Verlag Stuttgart.

Syntheses, crystal structures and photoluminescence of two Cd(II) coordination polymers derived from a flexible bipyridyl ligand

A flexible bipyridyl ligand 2,2?-bis(3-pyridylmethyleneoxy)-1, 1?-biphenylene (3,3?-bpp) was prepared for the construction of coordination frameworks. Two cadmium(II) coordination polymers, [Cd(mu-3,3?-bpp)2Br2]n (1) and [Cd(mu-3,3?-bpp)(mu-SCN)2]n (2) have been synthesized by the self-assembly between 3,3?-bpp and cadmium(II). 3,3?-bpp in 1 acts as a exo-bidentate ligand bridging CdBr2 unit to form a 1D double chains structure, while 3,3?-bpp and SCN – in 2 bridge Cd(II) centers resulting in a 1D zigzag chain structure. The solid-state fluorescent analyses show that complex 1 and 2 exhibit an intense broad emission band at 464 and 496 nm, respectively.

Neutral Nickel(II) Complexes Bearing Aryloxide Imidazolin-2-imine Ligands for Efficient Copolymerization of Norbornene and Polar Monomers

A series of novel aryloxide imidazolin-2-imine bidentate neutral Ni(II) complexes with different substituents on the imidazolin-2-imine ligand were synthesized and characterized. The complex Ni2 bearing a 2,6-diisopropylphenyl substituent adopted an almost square planar geometry, while the bulkier 2,6-bis(diphenylmethyl)-4-methylphenyl substituent ligated complex Ni3 was obtained in an allyl adduct base-free eta3 coordination mode. In the presence of B(C6F5)3, these Ni(II) complexes exhibited remarkably high activity (up to 2.7 ¡Á 107 g of PNB (mol of Ni)-1 h-1) and particularly good thermal stability toward the addition polymerization of norbornene. Most importantly, these catalysts were able to promote the direct copolymerization of norbornene with various polar monomers with high activity (?105 g (mol of Ni)-1 h-1), reasonable comonomer incorporation (0.14-3.08%), and high copolymer molecular weight (Mn up to 2.0 ¡Á 105). The strategy of installing a strongly electron donating imidazolin-2-imine ligand on the nickel complex demonstrates a great advantage for the copolymerization of an olefin with polar monomers.

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 250285-32-6, help many people in the next few years., Related Products of 250285-32-6

Crystal structure of a hybrid salt-cocrystal and its resolution by preferential crystallization: ((¡À)trans-N,N?- dibenzyldiaminocyclohexane)(2,3-dichlorophenylacetic acid)4

trans-N,N?-Dibenzyldiaminocyclohexane (B) crystallizes with 2,3-dichlorophenylacetic acid (AH); the crystal structure, resolved by using crystal X-ray diffraction, revealed an odd stoichiometry composed of H 2B2+, two A- and two AH forming an unexpected hybrid salt-cocrystal. As this compound is a stable conglomerate (i.e. every single crystal contains the enantiomerically pure cation H2B 2+, RR or SS), several preferential crystallization attempts (AS3PC) were performed in methanol and in THF and gave unexpected final enantiomeric excesses greater than 20% for the entrainment in methanol. These results suggest that the crystal growth mechanism preferentially involves building units composed of [H2B2+; 2A- and 2AH] or reconstruction of some crystal interfaces rather than a layer by layer construction.

Bis(dimethylamino)phosphorodiamidate: A Reagent for the Regioselective Cyclophosphorylation of cis-Diols Enabling One-Step Access to High-Value Target Cyclophosphates

Bis(dimethylamino)phosphorodiamidate (BDMDAP) enables an efficient and one-pot cyclophosphorylation of vicinal cis-diol moiety of polyol-organics of biological importance without the need for protecting group chemistry and is amenable to large-scale reactions. The utility of this reagent is demonstrated through the synthesis of high-value targets such as cyclic phosphates of myo-inositol, nucleosides, metabolites, and drug molecules.

Asymmetric synthesis of cyclic ethers by rearrangement of oxonium ylides generated from chiral copper carbenoids

Tetrahydrofuran-3-ones and tetrahydropyran-3-ones can be prepared enantioselectively by rearrangement of the ylide-type intermediates generated by the reaction of a chiral copper carbenoid with the oxygen atom of a pendant allylic ether. Cyclic ethers with enantiomeric excesses of up to 57% have been obtained using a copper complex of the enantiomerically pure diimine 1a for carbenoid generation.

A recyclable CO surrogate in regioselective alkoxycarbonylation of alkenes: Indirect use of carbon dioxide

Herein, we report a Pd-catalysed alkoxycarbonylation of alkenes based on the use of a recyclable CO2 reduction product, the crystalline and air-stable N-formylsaccharin, as a CO surrogate. The carbonylation proceeds under ambient conditions in an exceptionally complementary regioselective fashion yielding the desired branched products from styrene derivatives and valuable linear esters from alkyl-substituted alkenes.
