実験手順: To a solution of 388A (1.70 g, 7.35 mmol) and PPh3 (5.80 g, 22.1 mmol) in anhydrous THF (35 ml) was added t-butyl 2-hydroxyisobutyrate (3.83 ml, 22.1 mmol) followed by DEAD (3.47 ml, 22.1 mmol), the reaction mixture was stirred at rt for 19 h. More reagents PPh3 (1.16 g, 4.41 mmol), isobutyrate (0.77 ml, 4.41 mmol) and DEAD (0.69 ml, 4.41 mmol) were added, and the mixture was stirred for another 50 h, concentrated and purified by silica gel flash column chromatography to afford 388B (2.62 g, 96%) as a light pink crystalline solid (50%-80% CH2Cl2-hexanes). the mixture was stirred for another 50 h concentrated purified by silica gel flash column chromatography
