1448775-57-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1448775-57-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,4,8,7,7 and 5 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1448775-57:
(9*1)+(8*4)+(7*4)+(6*8)+(5*7)+(4*7)+(3*5)+(2*5)+(1*7)=212
212 % 10 = 2
So 1448775-57-2 is a valid CAS Registry Number.

Enantioselective alkylation of aldehydes using functionalized alkylboron reagents catalyzed by a chiral titanium complex

Kumar, Ravindra,Kawasaki, Hiroki,Harada, Toshiro

, p. 4198 - 4201 (2013/09/12)

A practical method is developed for the synthesis of enantioenriched functionalized secondary alcohols through catalytic enantioselective alkylation of aldehydes. Functionalized alkylboron reagents, [FG-(CH2) n]3B (FG = Br, TIPSO, PhtN, CO2iPr, and CN) prepared from terminal olefin precursors by hydroboration, undergo enantioselective addition to aldehydes in the presence of a catalytic amount (5 mol %) of 3-(3,5-diphenylphenyl)-H8-BINOL and excess titanium tetraisopropoxide to afford the corresponding functionalized alcohols in high enantioselectivities up to 99% ee.
