In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called Synthesis of C5-Allylindoles through an Iridium-Catalyzed Asymmetric Allylic Substitution/Oxidation Reaction Sequence of N-Alkyl Indolines, published in 2021-05-07, which mentions a compound: 1265884-98-7, mainly applied to allylindoline preparation enantioselective DFT study; allylindole preparation enantioselective DFT study; alkyl indoline allylic alc tandem reaction iridium catalyst, Reference of 5-(11bR)-Dinaphtho[2,1-d:1′,2′-f][1,3,2]dioxaphosphepin-4-yl-5H-dibenz[b,f]azepine.
Iridium/Bronsted acid cooperative catalyzed asym. allylic substitution reactions at the C5 position of indolines I (R = Bn, PMB; R1 = 2-Me, 2-Ph, 2,3-(Me)2, etc.) have been reported for the first time. The highly efficient protocol allows rapid access to various C5-allylated products (R/S)-II (Ar = C6H5, 2-BrC6H4, 2-naphthyl, etc.) and III in good to high yields (48-97%) and enantioselectivities (82% to >99% ee) with wide functional group tolerance. The transformations allow not only the formation of C5-allylindoline derivatives II but also the synthesis of C5-allylindoles III in good yields and excellent stereoselectivities via an allylation/oxidation reaction sequence.
This literature about this compound(1265884-98-7)Reference of 5-(11bR)-Dinaphtho[2,1-d:1′,2′-f][1,3,2]dioxaphosphepin-4-yl-5H-dibenz[b,f]azepinehas given us a lot of inspiration, and I hope that the research on this compound(5-(11bR)-Dinaphtho[2,1-d:1′,2′-f][1,3,2]dioxaphosphepin-4-yl-5H-dibenz[b,f]azepine) can be further advanced. Maybe we can get more compounds in a similar way.
