To a stirred solution of 25 (Nicolaou et al, 2016) (100 mg, 250 pmol, 1.0 equiv) in dry DMF (2 mL) at 0 C were added HATU (285 mg, 750 pmol, 3.0 equiv) followed by Et3N (200 pL, 1.50 mmol, 6.0 equiv) and the resulting mixture was stirred for 5 min at the same temperature. A solution of 26 (59.0 mg, 370 pmol, 1.5 equiv) in dry DMF (0.5 mL) was then added and the stirring was continued for 18 h while allowing the temperature to slowly rise to 23 C. The reaction mixture was diluted with H20 (5 mL) and the resulting solution was extracted with EtOAc (3 x 10 mL). The combined organic extracts were washed with brine (5 mL), dried over Na SCL and concentrated under reduced pressure. The obtained residue was purified by flash column chromatography (silica gel, 10 50% EtOAc in hexanes) to furnish 27 (113 mg, 210 pmol, 84% yield) as a white amorphous solid. 27: Rf= 0.50 (silica gel, 50% EtOAc in hexanes); [OC]D =-3.6 (c= 1.0, CHC13); FT-IR (film) VmaX: 2936, 1735, 1687, 1663, 1540, 1492, 1368, 1220, 1154, 1130, 1040, 771, 732 cnT1.

These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route 61367-07-5, its application will become more common.
