Reaction Steps

To a solution of methyl 3-[(3-buten-1-ylsulfonyl)(2-propen-1-yl)amino]-5-propylbenzoate (D135) (1 g, 2.8 mmol, 1 equiv) in CH2Cl2 (200 ml) was added bis(tricyclohexylphosphino)benzylidene ruthenium (IV) dichloride (117 mg, 0.14 mmol, 0.05 equiv) and the resulting solution was stirred at room temperature for 48 h then concentrated in vacuo. Purification of the residue by flash chromatography on silica gel (iso-hexane/AcOEt: 9:1) gave methyl 3-(1,1-dioxido-6,7-dihydro-1,2-thiazepin-2 (3H)-yl)-5-propylbenzoate (B117) (700 mg, 76%) as a pale purple oil. [M+H]+=324.4, RT=3.10 min.
