Calculate Digit Verification of CAS Registry Number 624728-32:
(8*6)+(7*2)+(6*4)+(5*7)+(4*2)+(3*8)+(2*3)+(1*2)=161
161 % 10 = 1
So 624728-32-1 is a valid CAS Registry Number.

Sequenced elimination-reduction and elimination-cyclopropanation reactions of 2,3-epoxyamides promoted by samarium diiodide. Synthesis of 2,3-dideuterioamides and cyclopropanamides

Concellón, José M.,Huerta, Mónica,Bardales, Eva

, p. 10059 - 10065 (2007/10/03)

An easy and general sequenced elimination/reduction or elimination/ cyclopropanation process promoted by samarium diiodide or/and CH 2I2/Sm provide an efficient method for synthesising 2,3-dideuterioamides 3 or cyclopropanamides 8, respectively. The transformations take place in high yields and with total or high selectivity from the easily available 2,3-epoxyamides. Graphical Abstract
