888725-60-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 888725-60-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,8,8,7,2 and 5 respectively; the second part has 2 digits, 6 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 888725-60:
(8*8)+(7*8)+(6*8)+(5*7)+(4*2)+(3*5)+(2*6)+(1*0)=238
238 % 10 = 8
So 888725-60-8 is a valid CAS Registry Number.

Indium-mediated diastereoselective allylation of D- and L-glyceraldimines with 4-bromo-1,1,1-trifluoro-2-butene: Highly stereoselective synthesis of 4,4,4-trifluoroisoleucines and 4,4,4-trifluorovaline

Chen, Qi,Qiu, Xiao-Long,Qing, Feng-Ling

, p. 3762 - 3767 (2007/10/03)

A practical and efficient route for the stereoselective synthesis of (2R,3S)- and (2S,3R)-4,4,4-trifluoroisoleucines and (2R,3S)-4,4,4- trifluorovaline was developed. Indium-mediated allylation of (R)-N-benzyl-2,3-O-isopropylideneglyceraldimine 7 with 4-bromo-1,1,1-trifluoro- 2-butene 4 gave the desired homoallylic amine 8 in high diastereoselectivity (>95% de) with moderate yield. The Cbz-protected (2R,35)-4,4,4- trifluoroisoleucine 14 and Boc-protected (2R,3S)-4,4,4-trifluorovaline 21 were then readily prepared from 8. In addition, following the same procedure, Cbz-protected (2S,3R)-4,4,4-trifluoroisoleucine 28, the enantiomer of 14, was prepared starting from (S)-N-benzyl-2,3-O-isopropylideneglyceraldimine 24.
