YieldReaction ConditionsOperation in experiment
85% at 40℃; for 48.0h;Inert atmosphere; To a solution of <strong>[76734-92-4]bis(trimethylsilyl) but-2-ynedioate</strong> (0.10 g, 0.37 mmol) in anhydrous methylene chloride (2 mL), cyclooctyne (0.06 g, 0.55 mmol) was added under nitrogen atmosphere. The mixture was stirred for 48 h at 40 C. The solvent and the excess of cyclooctyne were evaporated under reduced pressure to give 0.17 g (85%) of an unstable yellow oil. 1H-NMR (CDCl3): delta = 0.23 (s, 9H,CSi(CH3)3), 0.30 (s, 9H, CO2Si(CH3)3), 1.44-1.60 (m, 6H, CH2), 1.69-1.75 (m, 2 H, CH2), 2.31 (t,J = 6.4, 2 H, CH2), 2.48 (t, J = 7.1, 2 H, CH2). 13C-NMR(CDCl3): delta = -1.48 (q, CSi(CH3)3), -0.23 (q,OSi(CH3)3), 21.11 (t, CH2), 25.30 (t, CH2), 25.85 (t, CH2), 26.00 (t, CH2), 27.02 (t, CH2), 28.15 (t,CH2), 114.48 (s, C-3a), 133.46 (s, C=C-COOC), 146.84 (s, C=CCOOC), 158.85 (s, C-9a), 168.35 (s,CO), 171.09 (s, CO). Signal assignment and determination of the stereochemistry were supported by HMBC and NOESY experiments, respectively. 29Si-NMR (CDCl3): delta = -3.86 (CSi(CH3)3), 25.59(OSi(CH3)3). IR (CCl4): nu = 3010 (w), 2933 (s), 1785 (s), 1688 (s), 1249 (s) cm-1. HRMS: m/z calcd.for: C18H30O4Si2 ([M+Na]+): 389.1580, found: 389.1643.
