Bos, Pieter H.; Rudolph, Alena; Perez, Manuel; Fananas-Mastral, Martin; Harutyunyan, Syuzanna R.; Feringa, Ben L. published an article about the compound: (11bR)-N,N-Bis[(1R)-1-phenylethyl]dinaphtho[2,1-d:1′,2′-f][1,3,2]dioxaphosphepin-4-amine( cas:415918-91-1,SMILESS:C[C@@H](N(P1OC2=CC=C3C=CC=CC3=C2C4=C5C=CC=CC5=CC=C4O1)[C@@H](C6=CC=CC=C6)C)C7=CC=CC=C7 ).COA of Formula: C36H30NO2P. Aromatic heterocyclic compounds can be classified according to the number of heteroatoms or the size of the ring. The authors also want to convey more information about this compound (cas:415918-91-1) through the article.
A highly efficient method is reported for the asym. ring opening of oxabicyclic alkenes with organolithium reagents. Using a copper/chiral phosphoramidite complex together with a Lewis acid (BF3·OEt2), full selectivity for the anti isomer and excellent enantioselectivities were obtained for the ring opened products.
