147168-89-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 147168-89-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,7,1,6 and 8 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 147168-89:
(8*1)+(7*4)+(6*7)+(5*1)+(4*6)+(3*8)+(2*8)+(1*9)=156
156 % 10 = 6
So 147168-89-6 is a valid CAS Registry Number.

Asymmetric aldol reactions: A novel model for switching between chelation- and non-chelation-controlled aldol reactions

Yan, Tu-Hsin,Tan, Chang-Wei,Lee, Hui-Chun,Lo, Hua-Chi,Huang, Tzung-Yu

, p. 2613 - 2621 (1993)

A new camphor-based N-propionyloxazolidinethione provides remarkable levels of asymmetric induction for both chelation- and non-chelation-controlled aldol processes. While the aldol condensation of the derived di-n-butylboryl enolate with various aldehyde

Enantioselective addition of dialkylzinc to aromatic aldimines mediated by camphor-derived chiral β-amino alcohols

Huang, Wei-Ming,Uang, Biing-Jiun

supporting information, p. 998 - 1003 (2015/03/31)

The enantioselective addition of diethylzinc or dimethylzinc to N-(diphenylphosphinoyl)imines mediated by 1 or 2 could be achieved in high yields (70-97%) and enantioselectivities (85-98% ee). The catalytic loading of 1 or 2a could be reduced to 10 mol% f

A new chiral oxazoline derived from camphor and its conversion to (R)-2-methylalkanoic acids

Chandrasekhar, Sosale,Kausar, Amina

, p. 2249 - 2253 (2007/10/03)

(1S,5R,7R)-(-)-10,10-Dimethyl-3-ethyl-4-oxa-2-azatricyclo[5.2.1.01,5]dec-2-ene 2 was prepared in 95% yield from (1S)-1-amino-2-exo-hydroxyapocamphane 1. The chiral oxazoline could be alkylated (LDA/THF/-78°C/RX, RX=ethyl, n-propyl, n-butyl iodides or benzyl bromide) to 3 in 95% yield and >95% diastereoselectivity, and the products hydrolysed to (R)-2-methylalkanoic acids 4 (43-47% yield, 93-98% e.e.).
