Calculate Digit Verification of CAS Registry Number 77236-50:
(7*7)+(6*7)+(5*2)+(4*3)+(3*6)+(2*5)+(1*0)=141
141 % 10 = 1
So 77236-50-1 is a valid CAS Registry Number.

Reaktionen mit Aziridinen, XXII. Einstufensynthese von Pyrrolidonen durch Amidoethylierung einfacher Ester mit N-Acylaziridinen

Stamm, Helmut,Woderer, Anton,Wiesert, Wolfgang

, p. 32 - 48 (2007/10/02)

Sodium enolates of simple esters (2) react smoothly with N-acylaziridines (3) in THF forming 3-substituted 2-pyrrolidones 8.If the α-position of the ester carries more than one H-atom amidoethylated pyrrolidones can result.Whilst a simple butyrolactone behaves analogously amidoethylation of coumaranone furnished mono and bis amidoethyl derivatives of coumaranone besides a pyrrolidone. - In tert-butyl alcohol only extremly acidic esters like 1e and 1j could be amidoethylated.
