A highly efficient one-pot multistep process involving an asymmetric Pd(II)-catalyzed Overman rearrangement and a Ru(II)-catalyzed ring-closing metathesis reaction has been developed for the preparation of (R)- or (S)-aminocyclopenta-2-enes. The rapid strategy employed and the relatively mild conditions of the one-pot process allowed the multigram synthesis of the carbocycles in high enantiomeric excess (92% ee). The synthetic utility of these compounds was demonstrated by the stereoselective incorporation of hydroxyl groups, generating cis-4- and cis-5-aminocyclopenta-2-en-1-ols, important building blocks for medicinal chemistry.

supporting information; experimental part, p. 5457 - 5460 (2009/06/06)
(Chemical Equation Presented) A new route to (-)-agelastatin A is reported. The requisite nitrogen functionalities of the agelastatin core have been installed by intramolecular aziridination of an azidoformate and subsequent regioselective azidation, lead
Synthesis of 4-azacyclopent-2-enones and 5,5-dialkyl-4-azacyclopent-2- enones

Three different methods are reported for the preparation of 4-azacyclo-2-enones 1, two of which allow the preparation of the compounds in optically active form. In addition, a facile route to 4-aza-5,5- dimethylcyclopent-2-enones 2 is disclosed.
