Formation of 1-methylene-2-vinylcyclopropane by intramolecular -cycloalkylation reaction
摘要:
The synthesis of a substituted (Z)-2-(2-methylenecyclopropyl)vinyl N,N-dialkylcarbamate is presented. Via alpha-deprotonation of a 4-chloromethyl-2,4-dienyl carbamate and succeeding intramolecular S-E'-cycloalkylation reaction, the diastereomerically pure cyclopropane is formed.
