Purification Methods

Purify the alcohol by distillation, and the distllate crystallises on cooling. The hydrochloride has [] 20 +45.1o (c 4.8, *C6H6). The (-)-hydroperoxide has b58o/0.005mm, n D 1.5123,  D -2.14o, (l = 0.5dcm, neat). [Holding & Ross J Chem Soc 145 1954, Davies & Feld J Chem Soc 4637 1958.] The (±)-racemate has b 73o/0.05mm, and its 4-nitrophenylhydrazone has m 58o. [Beilstein 6 IV 3272.]

Check Digit Verification of cas no

The CAS Registry Mumber 22135-49-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,2,1,3 and 5 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 22135-49:
(7*2)+(6*2)+(5*1)+(4*3)+(3*5)+(2*4)+(1*9)=75
75 % 10 = 5
So 22135-49-5 is a valid CAS Registry Number.

New chiral lithium aluminum hydrides based on biphenyl-2,2′- bisfenchol (BIFOL): Structural analyses and enantioselective reductions of aryl alkyl ketones

Lange,Neud?rfl,Goldfuss

, p. 3704 - 3709 (2006)

A series of new chiral lithium aluminum hydrides based on BIFOL (biphenyl-2,2′-bisfenchol) and various alkyl alcohols (i.e., methanol, n-butanol, tert-butanol yielding BIFAl-H's) was synthesized and characterized by single crystal X-ray analyses. These investigations point to alkoxide redistribution for BIFAl-H-(O-tBu) (biphenyl-2,2′-bisfenchol aluminum hydride) species. The new BIFAl-H reagents are suitable to reduce aryl alkyl ketones with up to 62% ee. Computational transition structure analyses help to explain the experimentally observed enantioselectivities.

Enantioselective reduction of aryl ketones using LiBH4 and TarB-X: A chiral Lewis acid

Suri, Jeff T,Vu, Truong,Hernandez, Arturo,Congdon, Julie,Singaram, Bakthan

, p. 3649 - 3652 (2002)

High enantioselectivities are obtained using a tartaric acid-derived boronate ester in combination with lithium borohydride for asymmetric reduction of aryl ketones. The chiral Lewis acid, TarB-X, is easily prepared in 1 h, and the resulting alcohols are

Manganese catalyzed asymmetric transfer hydrogenation of ketones

Zhang, Guang-Ya,Ruan, Sun-Hong,Li, Yan-Yun,Gao, Jing-Xing

supporting information, p. 1415 - 1418 (2020/11/20)

The asymmetric transfer hydrogenation (ATH) of a wide range of ketones catalyzed by manganese complex as well as chiral PxNy-type ligand under mild conditions was investigated. Using 2-propanol as hydrogen source, various ketones could be enantioselectively hydrogenated by combining cheap, readily available [MnBr(CO)5] with chiral, 22-membered macrocyclic ligand (R,R,R',R')-CyP2N4 (L5) with 2 mol% of catalyst loading, affording highly valuable chiral alcohols with up to 95% ee.

An Enantioconvergent Benzylic Hydroxylation Using a Chiral Aryl Iodide in a Dual Activation Mode

Abazid, Ayham H.,Clamor, Nils,Nachtsheim, Boris J.

, p. 8042 - 8048 (2020/09/21)

The application of a triazole-substituted chiral iodoarene in a direct enantioselective hydroxylation of alkyl arenes is reported. This method allows the rapid synthesis of chiral benzyl alcohols in high yields and stereocontrol, despite its nontemplated nature. In a cascade activation consisting of an initial irradiation-induced radical C-H-bromination and a consecutive enantioconvergent hydroxylation, the iodoarene catalyst has a dual role. It initiates the radical bromination in its oxidized state through an in-situ-formed bromoiodane and in the second, Cu-catalyzed step, it acts as a chiral ligand. This work demonstrates the ability of a chiral aryl iodide catalyst acting both as an oxidant and as a chiral ligand in a highly enantioselective C-H-activating transformation. Furthermore, this concept presents an enantioconvergent hydroxylation with high selectivity using a synthetic catalyst.
