877681-24-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 877681-24-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,7,7,6,8 and 1 respectively; the second part has 2 digits, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 877681-24:
(8*8)+(7*7)+(6*7)+(5*6)+(4*8)+(3*1)+(2*2)+(1*4)=228
228 % 10 = 8
So 877681-24-8 is a valid CAS Registry Number.

Enantioselective addition of organozinc reagents to carbonyl compounds catalyzed by a camphor derived chiral γ-amino thiol ligand

Wu, Hsyueh-Liang,Wu, Ping-Yu,Cheng, Ying-Ni,Uang, Biing-Jiun

, p. 2656 - 2665 (2016/05/10)

In this article, the design and synthesis of the chiral camphor derived γ-amino thiol ligand 17 and its application in catalytic enantioselective carbon-carbon forming reactions through the addition of organozinc reagents to carbonyl compounds is described. The catalytic activity and enantioselectivity of ligand 17 is demonstrated in the enantioselective addition of various organozinc reagents to aldehydes and ketoesters, offering the corresponding alcohols in high yields and enantioselectivities. The role of the mercapto group in the highly enantioselective 1,2-addition reaction of organozincs to aldehyde is also discussed.

Asymmetric addition of dimethylzinc to α-ketoesters catalyzed by (-)-MITH

Wu, Hsyueh-Liang,Wu, Ping-Yu,Shen, Ying-Ying,Uang, Biing-Jiun

, p. 6445 - 6447 (2008/12/22)

(Chemical Equation Presented) This investigation describes the catalytic asymmetric addition of dimethylzinc to α-ketoesters in the presence of (-)-MITH (5) and triethyl borate as an additive to give the corresponding chiral α-hydroxy esters with good yie
