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, Research Support, Non-U.S. Gov’t, Chemistry – A European Journal called Application of Copper(II)-Dipyridylphosphine Catalyst in the Asymmetric Hydrosilylation of Simple Ketones in Air, Author is Zhang, Xi-Chang; Wu, Yan; Yu, Feng; Wu, Fei-Fei; Wu, Jing; Chan, Albert S. C., the main research direction is ketone hydrosilylation copper pyridylphosphine catalyst; secondary alc asym preparation.Reference of (R)-2,2′,6,6′-Tetramethoxy-4,4′-bis(diphenylphosphino)-3,3′-bipyridine.
A copper(II) salt/chiral dipyridylphosphine/PhSiH3 system (see scheme) acts as a very effective and practical catalyst for the asym. reduction of heteroaromatic and other types of ketones in air with good-to-excellent enantioselectivities (up to 94 %), giving many chiral alcs. that are intermediates for physiol. active compounds Remarkable temperature effects were observed for some heteroaromatic ketones.
