that permits ring-closingmetathesis and bifunctional chiral amine (thio)urea-catalyzed Michael addition reactions to proceed in a one-pot fashion. The process offers an alternative approach to the synthesis of structurally diverse chiral cyclopentanes in good yields and good enantioselectivities. A relay strategy is described that permits ring-closingmetathesis and bifunctional chiral amine (thio)urea-catalyzed
