| Description: |
Cyclopropane- and alkylcyclopropane-annelated methyl imidazolidinecarboxylates 5 are formed from unsubstituted 1-H and from 2'-substituted methyl 2-chloro-2-cyclopropylideneacetates (1-R) and N,N',N ''-triarylguanidines (2) in a domino process consisting of a Michael addition and an immediately ensuing ring closure by intramolecular nucleophilic substitution in moderate to very good yields (30-95%, 8 examples). The products 5 with alkyl substituents on the spirocyclopropane moiety are formed diastereoselectively. ((c) Wiley-VCH Verlag GmbH & Co.
