69257-04-1 Usage

Chemical Properties

white to light yellow crystal powde

Purification Methods

Dissolve the chloride in the minimum volume of H2O and add absolute Me2CO. Filter it off and dry it in a vacuum. It can also be recrystallised from hot EtOH or EtOH/Et2O. (A good chiral phase transfer catalyst-see above) [Colonna et al. J Chem Soc, Perkin Trans 1 547 1981, Imperali & Fisher J Org Chem 57 757 1992]. [Beilstein 23 H 446.] See cinchonidine below.

Check Digit Verification of cas no

The CAS Registry Mumber 69257-04-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,9,2,5 and 7 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 69257-04:
(7*6)+(6*9)+(5*2)+(4*5)+(3*7)+(2*0)+(1*4)=151
151 % 10 = 1
So 69257-04-1 is a valid CAS Registry Number.

Preparation method of optically pure 1, 1'-spirobiindane-6, 6'-diol derivative

-

Paragraph 0020-0022, (2019/03/17)

The invention discloses a preparation method of an optically pure 1, 1'-spirobiindane-6, 6'-diol derivative. The derivative is shown in the formula I. The optically pure 1, 1'-spirobiindane-6, 6'-diolderivative is prepared from optically pure N-benzylcinchonidinium chloride as an inclusion main body and a racemic 1, 1'-spirobiindane-6, 6'-diol derivative as a guest through an inclusion and resolution method. The novel method can acquire the 1, 1'-spirobiindane-6, 6'-diol derivative with high optical purity and chemical purity and acquire two structures in a high yield, has simple separation and purification processes, realizes recovery and recycling of a lot of a resolving agent, is simple and efficient, realizes a low cost and is suitable for industrial promotion. The optically pure 1, 1'-spirobiindane-6, 6'-diol derivative is a key raw material for the preparation of chiral spiro ligands or catalysts.

Asymmetric Induction in the Michael Reaction by Means of Chiral Phase-transfer Catalysts derived from Cinchona and Ephedra Alkaloids

Colonna, Stefano,Re, Alberto,Wynberg, Hans

, p. 547 - 552 (2007/10/02)

Asymmetric induction in the Michael reaction has been achieved using alkaloidonium salts in a two-phase system with optical yields of up to 36 and 26percent in the addition to αβ-unsaturated ketones of thiols and nitroalkanes respectively.The presence of a hydroxy-group β to the 'onium function is essential to achieve substantial asymmetric syntheses.
