Unsymmetrical maleates from stereoselective decomposition of diazoesters using Grubbs' 2nd-generation Ru carbene catalyst
A range of unsymmetrical cis-2-ene-1,4-diesters has been synthesized from two different alpha-diazoacetates using Grubbs' 2nd-generation catalyst (0.5 mol%, RT, 12-16 h). Formation of the enediesters occurred with high stereoselectivity (>= 95% cis). (c) 2006 Elsevier B.V. All rights reserved.
