33489-21-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 33489-21-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,3,4,8 and 9 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 33489-21:
(7*3)+(6*3)+(5*4)+(4*8)+(3*9)+(2*2)+(1*1)=123
123 % 10 = 3
So 33489-21-3 is a valid CAS Registry Number.

Stereoselective synthesis of alicyclic ketones: A hydrogen borrowing approach

Armstrong, Roly J.,Akhtar, Wasim M.,Frost, James R.,Christensen, Kirsten E.,Stevenson, Neil G.,Donohoe, Timothy J.

, (2019)

A highly diastereoselective annulation strategy for the synthesis of alicyclic ketones from diols and pentamethylacetophenone is described. This process is mediated by a commercially available iridium(III) catalyst, and provides efficient access to a wide range of cyclopentane and cyclohexane products with high levels of stereoselectivity. The origins of diastereoselectivity in the annulation reaction have been explored by a series of control experiments, which provides an explanation for how each stereocentre around the newly forged ring is controlled.

Stereoselective Michael additions of titanium "ate" complexes of ketone and ester enolates

Bernardi, Anna,Dotti, Pierfranco,Poli, Giovanni,Scolastico, Carlo

, p. 5597 - 5606 (2007/10/02)

The conjugate addition of Ti "ate" complexes of ketone and ester enolates to α,β-unsaturated carbonyl compounds was studied. The reaction was found to be highly regio- and stereoselective. Compared to the lithium enolates, ketone enolate Ti complexes show
