(11bS)-4-Hydroxy-2,6-di(phenanthren-9-yl)dinaphtho[2,1-d:1′,2′-f][1,3,2]dioxaphosphepine 4-oxide (cas: 1043567-32-3) belongs to chiral phosphine ligands. Phosphine-catalyzed asymmetric reactions are now powerful and versatile tools for the construction of C–C, C–N, C–O, and C–S bonds and for the syntheses of functionalized carbocycles and heterocycles. Trivalent phosphorus compounds called phosphines have a tetrahedral electron-group geometry which makes them structurally analogous to amines.Recommanded Product: (11bS)-4-Hydroxy-2,6-di(phenanthren-9-yl)dinaphtho[2,1-d:1′,2′-f][1,3,2]dioxaphosphepine 4-oxide

An acid-catalyzed formal [3+2] cyclization/N,O-ketalization of in-situ formed ortho-alkynyl quinone methides (o-AQMs) and tryptophol derivatives was developed. With this method, a series of functionalized 2,3-cyclopentanoindoline derivatives were effectively synthesized in good yields with excellent diastereoselectivities under mild conditions. In this reaction, o-AQMs formally serves as synthetic equivalent of the 1,3-dipole, and the process involves a tandem 1,4-addition/dearomatization/1,2-shift/aromatization sequence of tryptophol. In the experiment, the researchers used many compounds, for example, (11bS)-4-Hydroxy-2,6-di(phenanthren-9-yl)dinaphtho[2,1-d:1′,2′-f][1,3,2]dioxaphosphepine 4-oxide (cas: 1043567-32-3Recommanded Product: (11bS)-4-Hydroxy-2,6-di(phenanthren-9-yl)dinaphtho[2,1-d:1′,2′-f][1,3,2]dioxaphosphepine 4-oxide).
