217969-68-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 217969-68-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,7,9,6 and 9 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 217969-68:
(8*2)+(7*1)+(6*7)+(5*9)+(4*6)+(3*9)+(2*6)+(1*8)=181
181 % 10 = 1
So 217969-68-1 is a valid CAS Registry Number.

Diastereoselective radical cyclization of bromoacetals (Ueno-Stork reaction) controlled by the acetal center

Villar, Felix,Renaud, Philippe

, p. 8655 - 8658 (1998)

The stereochemistry of the 5-exo-trig cyclization of bromoacetals (Ueno- Stork cyclization) can be controlled from the stereogenic acetal center. High stereoselectivities have been observed for the formation of 4-substituted tetrahydrofurans. Preparation

Highly stereoselective radical cyclization of haloacetals controlled by the acetal center

Villar, Felix,Kolly-Kovac, Tanja,Equey, Olivier,Renaud, Philippe

, p. 1566 - 1577 (2007/10/03)

A systematic investigation of radical haloacetal cyclizations (Ueno-Stork reaction) where the acetal center is the unique stereogenic element is reported. This highly diastereoselective reaction can be used for the preparation of polysubstituted tetrahydrofurans and γ-lactones. We report herein the full experimental details of reactions where up to three new chiral centers are created. To demonstrate the potential of this approach, short syntheses of (+)-eldanolide and of tricyclic acetals related to biologically active lignans have been achieved.
