Reaction Conditions

Reaction Steps

A solution of TBAF in THF (4.3 mL of a 1N solution, 4.3 mmol) was added to a rapidly stirred solution of 129 (0.37 g, 0.9 mmol) in THF (10 mL) and the reaction mixture heated to 35° C. for 2 h. The reaction mixture was diluted with EtOAc (50 mL), dried over anhydrous MgSO4, filtered and removal of excess solvent by rotary evaporation under reduced pressure afforded the product as a brown oil (0.18 g, 0.7 mmol, 78%). H1 NMR (CDCl3) mixture of C11/C11′R/S carbinolamine methyl ethers δ 7.08 (s, 1H), 4.43 (d, 1H, J=8.79 Hz), 4.05-3.23 (m, 12H), 2.3-1.48 (m, 4H).
