Versuchsvorschrift

(1R,2S)-ethyl 1-((2S,4R)-1-((S)-5-(allyloxy)-2-(tert-butoxycarbonylamino)pentanoyl)-4-hydroxypyrrolidine-2-carboxamido)-2-vinylcyclopropanecarboxylate (3.55 g, 6.78 mmol) in toluene (750 mL) was degassed by bubbling a stream of nitrogen through the reaction for 1 hr at rt. (5-chloro-2-isopropoxybenzylidene)(1,3-dimesitylimidazolidin-2-yl)ruthenium(V)chloride (0.090 g, 0.14 mmol) was added to the mixture and the mixture was heated to 68° C. (oil bath) and stirred at this temperature for 4 hrs. After removal of solvent, the residue was purified by chromatography (Ethyl acetate:MeOH=40:1) to give (2R,6S,13aS,14aR,16aS,Z)-ethyl 6-(tert-butoxycarbonylamino)-2-hydroxy-5,16-dioxo-2,3,5,6,7,8,9,11,13a,14,14a,15,16,16a-tetradecahydro-1H-cyclopropa(e)pyrrolo[2,1-i][1,7,10]oxadiazacyclopentadecine-14a-carboxylate as off white solid (0.84 g, 25%).
