反应机理
反应操作
2-Methylene-4-(methoxymethoxy)-8ab-(phenylsulfonyl)-3ab-decahydroazulene (3). To Pd(OAc)2 (15 mg, 0.06 mmol) and P(OiPr)3 (101 mg, 0.487 mmol) in PhMe (2 mL) was added 1 (1.05 g, 3.54 mmol) in PhMe (2 mL) followed at 60 ℃ by 2 (0.95 g, 5.3 mmol). After 40 h at 80 ℃, chromatography (3:1, hexane:EA, Rf =0.33) gave 1.15 g of 3 (93%).
