178180-47-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 178180-47-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,8,1,8 and 0 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 178180-47:
(8*1)+(7*7)+(6*8)+(5*1)+(4*8)+(3*0)+(2*4)+(1*7)=157
157 % 10 = 7
So 178180-47-7 is a valid CAS Registry Number.

Experimental and theoretical studies of the internal stereodifferentiation occurring during the lithiation of β-stereogenic alkyl carbamates. Kinetic resolutions by (-)-sparteine-mediated deprotonation

Haller, Jan,Hense, Thomas,Hoppe, Dieter

, p. 489 - 499 (2007/10/03)

The deprotonation of β-stereogenic alkyl carbamates 8 with sec-butyllithium/TMEDA proceeds kinetically controlled with differentiation between the diastereotopic protons at the α-methylene group. The lithium intermediates 9A and 9B are trapped by electrophiles to give carboxylic acid esters 10A/ B and stannanes 11A/B, 13A/B. The diastereomeric ratio of A to B is independent of the electrophile. The highest efficiency is achieved with β-aryl-β-alkyl-substituted starting compounds 8d-f. The trends in the experimentally observed diastereoselectivities are reflected by the results of semiempirical PM3 calculations on the transition states of the deprotonation reaction. - As a result of double stereodifferentiation, application of the chiral base sec-butyllithium/(-)-sparteine gives rise to efficient kinetic resolution of racemic alkyl carbamates.
