文摘
Unusual reactions of 1-(alk-1-ynyl)-1-chlorocyclopropanes with lithium derivatives of 1,2-diaminoethane, 1,3-diaminopropane and 1-methylamino-3-aminopropane in THF at 20 °C give previously unknown 5-methylenehexahydropyrrolo[1,2-a]imidazoles and 6-methyleneoctahydropyrrolo[1,2-a]pyrimidines with up to 60 % yields.
