Most of the natural products isolated at present are heterocyclic compounds, so heterocyclic compounds occupy an important position in the research of organic chemistry. A compound: 221012-82-4, is researched, SMILESS is COC(C=C1P(C2=CC=CC=C2)C3=CC=CC=C3)=NC(OC)=C1C4=C(OC)N=C(OC)C=C4P(C5=CC=CC=C5)C6=CC=CC=C6, Molecular C38H34N2O4P2Journal, Article, Chemistry – A European Journal called Rhodium-Catalyzed Asymmetric [2+2+2] Cycloaddition of 1,6-Enynes with Racemic Secondary Allylic Alcohols through Kinetic Resolution, Author is Suzuki, Shunsuke; Shibata, Yu; Tanaka, Ken, the main research direction is bicyclic cyclohexene preparation enantioselective diastereoselective; enyne allylic alc cycloaddition reaction rhodium catalyst; allylic alcohols; asymmetric [2+2+2] cycloaddition; enynes; kinetic resolution; rhodium.Recommanded Product: 221012-82-4.
It has been established that a cationic rhodium(I)/P-phos complex catalyzes the asym. [2+2+2] cycloaddition of 1,6-enynes R1CCCH2ZCH2CH(=CH2)R2 (R1 = Me, Ph, pentyl; R2 = H, Me) with racemic secondary allylic alcs. R3CH(OH)CH=CH2 to produce the corresponding chiral bicyclic cyclohexenes I, possessing three stereogenic centers, as a single diastereomer with excellent ee values. Mechanistic experiments revealed that the present cycloaddition proceeds through the kinetic resolution of the racemic secondary allylic alcs., in which one enantiomer preferentially reacts with the 1,6-enyne.
