477953-48-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 477953-48-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,7,7,9,5 and 3 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 477953-48:
(8*4)+(7*7)+(6*7)+(5*9)+(4*5)+(3*3)+(2*4)+(1*8)=213
213 % 10 = 3
So 477953-48-3 is a valid CAS Registry Number.

Studies on the synthesis of (-)-gymnodimine. Subunit synthesis and coupling

White, James D.,Quaranta, Laura,Wang, Guoqiang

, p. 1717 - 1728 (2007/10/03)

Two principal subunits of the marine algal toxin (-)-gymnodimine were synthesized. A trisubstituted tetrahydrofuran representing C10-C18 of the toxin was prepared via a highly stereoselective iodine-mediated cyclization of an acyclic alkene bearing a bis-

Silicon tether-aided coupling metathesis: Application to the synthesis of attenol A

Van De Weghe, Pierre,Aoun, Darina,Boiteau, Jean-Guy,Eustache, Jacques

, p. 4105 - 4108 (2007/10/03)

(matrixpresented) A new synthesis of attenol A is described. Key features of this work include a crucial silicon tether-aided coupling metathesis step and the use of iodoetherification as an efficient protection method for 1,5-ene-ols.

Total Synthesis of Tautomycin

Oikawa, Masato,Ueno, Tohru,Oikawa, Hideaki,Ichihara, Akitami

, p. 5048 - 5068 (2007/10/02)

A convergent stereocontrolled synthesis of the antifungal antibiotic tautomycin, a potent protein phosphatases inhibitor, has been achieved first via key aldol coupling of two large subunits, a right-hand C1-C21 ketone and a left-hand aldehyde (left from C22).The C1-C10 segment was synthesized through a remote stereochemical control process using a spiroketal template.After joining with the C11-C18 segment, the spiroketal moiety was selectively constructed.Then the right-hand C1-C21 ketone was synthesized via Roush asymmetric crotylboration.The left-hand aldehyde was prepared from a C21-C26 segment and a dialkylmaleic anhydride segment.Completely stereoselective assemblage of the two subunits, the right-hand and the left-hand, was achieved by employing the Mukaiyama aldol reaction.Further functional group manipulation including desilylation, oxidation at C2, and deprotection of tert-butyl ester with concomitant anhydride formation provided tautomycin which was identical with the natural product.As a preliminary study, derivatizations and degradation of the natural product were also examined to support the total synthesis.
