Procedure

A solution of (1R,2S)-methyl 1-((2S,4R)-1-((2S,3R)-2-((tert-butoxycarbonyl)amino)-3,5-dimethylnon-8-enoyl)-4-hydroxypyrrolidine-2-carboxamido)-2-vinylcyclopropanecarboxylate (2.68 g, 5 mmol) in DCE (600 mL) was sparged with nitrogen for 30 min. and then Hoveyda-Grubbs Catalyst 2nd Generation (0.189 g, 0.300 mmol) was added and the reaction heated to 80° C. for 2 hrs. The reaction was concentrated and purified by flash chromatography on silica gel (20-60% Acetone in hexanes) to give 2.1 g of the product (2R,6S,7R,13aS,14aR,16aS,Z)-methyl 6-((tert-butoxycarbonyl)amino)-2-hydroxy-7,9-dimethyl-5,16-dioxo-1,2,3,5,6,7,8,9,10,11,13a,14,14a,15,16,16a-hexadecahydrocyclopropa[e]pyrrolo[1,2-a][1,4]diazacyclopentadecine-14a-carboxylate. MS: MS m/z 530.18 (M++23).
