Application of 39648-67-4. Let¡¯s face it, organic chemistry can seem difficult to learn. Especially from a beginner¡¯s point of view. Like 39648-67-4, Name is (R)-4-Hydroxydinaphtho[2,1-d:1′,2′-f][1,3,2]dioxaphosphepine 4-oxide. In a document type is Article, introducing its new discovery.
Catalytic asymmetric chemodivergent arylative dearomatization of tryptophols
The first catalytic asymmetric arylative dearomatization of tryptophols has been established. By using quinone imine ketals as aryl group surrogates and modulating the reaction conditions, the cascade reaction of tryptophols with quinone imine ketals in the presence of chiral phosphoric acid afforded two series of arylative dearomatization products with generally high yields (up to 99%), and excellent diastereo- and enantioselectivities (all > 95 : 5 dr, 90% to 99% ee) in a chemoselective manner.
