    • One-pot procedure for 10a from 7a: To a stirred solution of compound (7a) (38.6 mg, 0.108 mmol) in 1,1,2,2-tetrachloroethane (2.0 mL), borontrifluoride etherate (0.36 mL, 2.9 mmol) was added at 0°C under argon atmosphere, and then the reaction mixture was heated to 120°C for 2 h. To the reaction mixture, dimethoxypropane (0.2 mL, 1.6 mmol) was added at 120°C, and heated at 120°C for 1 h. The reaction mixture was worked up as described above to afford the product (10a, 16.5 mg) in 77% yield
