実験手順

A suspension of the phenol 58 (1.0 g, 3.5 mmol), 1-oxa-spiro[2.7]decane (0.5 g, 3.2 mmol) and Cs2CO3 (1.14 g, 3.5 mmol) in DMSO (4 mL) was heated at 120° C. for 16 h. After completion of reaction, the mixture was quenched by the addition of 1N HCl and extracted with DCM. The organic layer was dried over anhydrous Na2SO4, filtered and concentrated under reduced pressure. Purification by flash chromatography (0 to 10% 7N NH3/methanol—CH2Cl2) afforded 2-(3-(3-((1-hydroxycyclooctyl)methoxy)phenyl)propyl)isoindoline-1,3-dione as yellow oil. Yield (1.057 g, 72%): 1H NMR (400 MHz, CDCl3) δ 7.10-7.36 (m, 2H), 6.40-6.80 (m, 6H), 3.69 (s, 2H), 2.10-2.45 (m, 2H), 1.30-2.0 (m, 18H).
