実験手順: The reaction was carried out similarly as described in the preparation of compound 101, using compound 432 (2.06 mmol) and compound 408 (2.06 mmol). The crude product was purified by continuous gradient flash chromatography using EtOAc/petroleum ether (40-60) 50:50 to 50:50 as the eluent to afford the title compound. The crude product was purified by continuous gradient flash chromatography

実験手順: The reaction was carried out similarly as described in the preparation of compound 408, using toluene-4-sulfonic acid 2,2-dimethyl-[1,3]dioxolan-4-ylmethyl ester (37.8 mmol). The crude product was purified by continuous gradient flash chromatography using EtOAc/petroleum ether (40-60) 0:100 to 20:80 as the eluent to afford the title compound as colourless foam. The crude product was purified by continuous gradient flash chromatography

実験手順: A mixture of 2-(2-bromo-ethoxy)-tetrahydro-pyran (1.00 mL, 6.62 mmol), NaN3 (4.34 g, 66 mmol) and tetrabutylammonium iodide (245 mg, 0.66 mmol) in DMF (7.0 mL) was stirred at RT for 18 h. The reaction mixture was poured into a mixture of EtOAc/water. The organic phase was washed with water, brine and then dried (MgSO4), filtered and concentrated in vacuo to give the crude product. The crude product was purified by continuous gradient flash chromatography using EtOAc/petroleum ether (40-60) 0:100 to 20:80 as the eluent to afford the title compound as colourless oil. The organic phase was washed with water, brine dried (MgSO4) filtered concentrated in vacuo to give the crude product The crude product was purified by continuous gradient flash chromatography
