Synthesis of chiral a-substituted a-amino acid and amine derivatives through Ni-catalyzed asymmetric hydrogenation

Highly efficient Ni-catalyzed asymmetric hydrogenation of cyclicN-sulfonyl ketimino esters was, for the first time, successfully developed, providing various chiral a-monosubstituted a-amino acid derivatives with excellent results (97-99% yields, 90 to >99% ee). CyclicN-sulfonyl ketimines were also hydrogenated well to afford chiral amine derivatives with 98-99% yields and 97 to >99% ee. The gram-scale asymmetric hydrogenation was performed well with 85% yield and 99% ee using only 0.2 mol% catalyst.

Organic photoelectric material containing butterfly structure and preparation method and application thereof

The invention relates to an organic photoelectric material containing a butterfly structure and a preparation method and application thereof. The organic photoelectric material is represented by the following formula I shown in the specification, wherein Ar1 and Ar2 are the same or different, Ar1 and Ar2 exist at the same time or partially exist, and Ar1 and Ar2 are selected from one of hydrogen and substituted or unsubstituted polycyclic conjugated aryl with the carbon atom number of 4-36. The organic photoelectric material has the characteristics that molecules are not easy to crystallize and aggregate, and the film-forming property is good; and the 3D rigid structure in the molecule can improve the thermal stability of the luminescent material, and the material is applied to the organiclight-emitting device as the luminescent material, so that the maximum current efficiency of the organic light-emitting device is improved, the turn-on voltage of the organic light-emitting device isreduced, and the service life of the organic light-emitting device is greatly prolonged.

Facile synthesis of 2,3-disubstituted benzofurans via DBU-promoted intramolecular annulation of ortho oxyether aroylformates

A facile synthesis of 2,3-disubstituted benzofurans from ortho oxyether aroylformates has been developed. Under the mediation of DBU, the intramolecular annulation of ortho oxyether aroylformates proceeds smoothly to provide the corresponding 2,3-disubsti

A 2 - (2-hydroxy-phenyl) - 2-phenoxyacetic acid ester synthetic method

The invention discloses a synthetic method for 2-(2-hydroxyphenyl)-2-oxyacetate. The method comprises the following steps: taking cyclohexanone and glyoxylate as raw materials, producing an Aldol condensation reaction through catalysis at a room temperatu

Synthesis of quaternary carbon centered chromans from the reactions of ethyl 2-(2-hydroxyaryl)-2-oxoacetates with allenic ester or allenic sulfone catalyzed by tertiary phosphine and SPTS

Cyclization reactions of ethyl 2-(2-hydroxyaryl)-2-oxoacetates with ethyl 2,3-butadienoate and allenylsulfone proceeded smoothly in the presence of tertiary phosphine and sodium p-toluenesulfinate (SPTS) to give the corresponding quaternary carbon centere

Ω-OXYGENATED PRENYLATED COUMARINS FROM FERULA COMMUUNIS

From the toxic variety of Ferula communis, derivatives of the prenylated coumarins ferulenol and ferperin bearing an oxygen function (hydroxyl, acetoxyl, aldehydic carbonyl) at the ω-position have been isolated.The structures of the coumarins were established by spectral methods and by chemical reactions.Photooxygenation of ferulenol and (E)ω-hydroxyferulenol gave o-hydroxyphenylglyoxylic esters, resulting from the oxidative decarbonylation of the 4-hydroxycoumarinic nucleus and losss of the prenyl side chain.Ethyl o-hydroxyphenylglyoxylacetate was also isolated from the plant extract, suggesting that a reaction of this type might be responsible for the degradation of the prenylated coumarins in plant samples and extracts of Ferula commuunis. Key Word Index-- Ferula communis; Umbelliferae; prenylated coumarins; ferulenol; ferprenin.
