    • General Procedure for Olefin Metathesis, Synthesis of 8c A flask was charged with toluenesulfonyl amine 7c (91 mg, 0.3 mmol) and CH 2Cl2 (90 mL, Ethene gas was bubbled through the solution for 20 s. Then, Grubbs I catalyst (25 mg, 0.03 mmol) was added to the reaction. A balloon filled with ethene gas was placed over the flask and the reaction was allowed to stir at r.t. overnight. The reaction mixture was then concentrated and subjected to column chromatography eluting PE-Et2O (19:1 to 4:1) to furnish 8c as a colourless oil (89 mg, 99% yield. 1H NMR (400 MHz, CDCl3, δ, 1.11 (ddd, 1 H, CH2CHN, J, 13.5, 8.0, 4.0 Hz, 1.33 (dd, 1 H, H2CHCHC=CH, J, 14.5, 7.5 Hz, 1.66 (dt, 1 H, H2CHCHC=CH, J, 12.0, 6.5 Hz, 2.13 (td, 1 H, CH2CHN, J, 16.0, 13.5 Hz, 2.41 (s, 3 H, CH3, 2.41-2.43 (m, 1 H, HCHC=CH, 2.60-2.65 brm, 1 H, HC
