133285-28-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 133285-28-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,3,2,8 and 5 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 133285-28:
(8*1)+(7*3)+(6*3)+(5*2)+(4*8)+(3*5)+(2*2)+(1*8)=116
116 % 10 = 6
So 133285-28-6 is a valid CAS Registry Number.

Diisopropyl tartrate modified (E)-γ-[(cyclohexyloxy)dimethylsilyl]-and (E)-γ-(dimethylphenylsilyl)allylboronates: Chiral reagents for the enantio-and diastereoselective synthesis of anti 1,2-diols and 2-butene-1,4-diols via the formal α- and γ-hydroxyallylation of aldehydes

Roush, William R.,Grover, Paul T.

, p. 1981 - 1998 (2007/10/02)

Enantioselective synthesis of 4-substituted (E)-2-butene-1,4-diols and anti 1,2-diols are described. Highly diastereoselective reactions of aldehydes and the chiral PhMe2Si- and (C6H11O)Me2Si-substituted allylboronates 25 and 26 provide anti homoallylic 29 and 50, respectively. Epoxidation of 29 with dimethyl dioxirane followed by acid catalyzed Petersen rearrangement of the intermediate epoxysilanols provides butee-1,4-diols 27 with excellent enantioselectivity (81-87% e.e.). Tamao oxidation of 50 provides anti diols 22 (64-72% e.e). These procedures give excellent results especially in matched double asymmetric reactions with a range of oxygenated, chiral aldehydes (Figures 1 and 2). These methods promise to find application in diastereoselective syntheses of carbohydrates from acyclic precursors.
