Enantiomerically pure (R)-3,3′-bis(9-phenanthryl)-1,1′-binaphthalene-2,2′-diyl hydrogen phosphate (I) is prepared in four steps from (R)-(+)-2,2′-bis(methoxymethoxy)-1,1′-binaphthyl (II). Thus, regioselective ortho-iodination of II with I2 and BuLi in THF gives 40% of the corresponding diiodo compound, which then undergoes Suzuki coupling with 9-phenanthreneboronic acid in 91% yield. Next, the OMOM ethers are cleaved with HCl to give 99% of the corresponding diol, followed by treatment with POCl3 to give 91% I. The preparative information is followed by a short review of the use of I and related enantiomerically pure binaphthalene hydrogen phosphates as chiral Bronsted acids for multicomponent reactions. In addition to this study using (R)-3,3′-Diiodo-2,2′-bis(methoxymethoxy)-1,1′-binaphthalene, there are many other studies that have used (R)-3,3′-Diiodo-2,2′-bis(methoxymethoxy)-1,1′-binaphthalene(cas: 189518-78-3Application In Synthesis of (R)-3,3′-Diiodo-2,2′-bis(methoxymethoxy)-1,1′-binaphthalene) was used in this study.
(R)-3,3′-Diiodo-2,2′-bis(methoxymethoxy)-1,1′-binaphthalene(cas: 189518-78-3) belongs to organic iodides. Generally organic iodides can be divided into two classes of alkyl iodides and aryl iodides. Typical reactions of alkyl iodides include nucleophilic substitution, elimination, reduction, and the formation of organometallics.Application In Synthesis of (R)-3,3′-Diiodo-2,2′-bis(methoxymethoxy)-1,1′-binaphthalene
