Cheng, Ke published the artcileChiral phosphoric acid catalyzed enantioselective allylation of aldehydes with allyltrichlorosilane, HPLC of Formula: 297752-25-1, the publication is Chinese Journal of Chemistry (2011), 29(8), 1669-1671, database is CAplus.
Easily accessible chiral phosphoric acid 1b has been applied as efficient organocatalyst for the asym. allylation of aldehydes with allyltrichlorosilane. In the presence of 20 mol% of 1b, the allylation of a broad range of aldehydes proceeded smoothly to give the corresponding homoallylic alc. with up to 87% ee and 97% yield.
Chinese Journal of Chemistry published new progress about 297752-25-1. 297752-25-1 belongs to chiral-phosphine-ligands, auxiliary class Chiral Phosphoric Acids, name is (R)-4-Hydroxy-8,9,10,11,12,13,14,15-octahydrodinaphtho[2,1-d:1′,2′-f][1,3,2]dioxaphosphepine 4-oxide, and the molecular formula is C20H21O4P, HPLC of Formula: 297752-25-1.
