Description / Table of Contents:
cis-1,2-Cyclobutanediamines by Photosensitized Cycloaddition of 1,3-Diacetyl-4-imidazolin-2-ones to Olefins1,3-Diacetyl-4-imidazolin-2-one (8) reacts photosensitized with ethylene in a [2 + 2]-cycloaddition reaction yielding 9. Hydrolysis of 9 leads to cis-1,2-cyclobutanediamine (1) via the cyclic urea 2. By analogy, derivatives of 1 can be obtained using other olefins or alkyl substituted 1,3-diacetyl-imidazolinones (23 and 24).
Notes:
1,3-Diacetyl-4-imidazolin-2-on (8) reagiert photosensibilisiert mit Ethylen in einer [2 + 2]-Cyclo-addition unter Bildung von 9. Dessen Hydrolyse führt über den Harnstoff 2 zum cis-1,2-Cyclobutandiamin (1). Analog lassen sich mit anderen Olefinen oder alkylsubstituierten 1,3-Diacetyl-imidazolinonen (23 und 24) Derivate von 1 herstellen.
