A resolution of 22 (1.00 g, 731 ol) in CH2 Cl2 (14.six mL) was treated with DMP (467 mg, 1.ten mmol) plus the resulting mixture was stirred for 2 h at area temperature. A 10 aqueous Na2 S2 O3 answer (50 mL) was added, the aqueous phase was separated and SBP-3264 medchemexpress extracted with CH2 Cl2 (3 50 mL). The combined organic phases had been dried more than Na2 SO4 and concentrated in vacuo.

To a answer of phosphonate 9 (34.1 mg, 110 ol) in THF (1.35 mL) at 0 C was dropwise added a LiHMDS answer (220 , 1M in THF) and the resulting mixture was stirred for 30 min at area temperature, cooled to 0 C, and treated with a resolution of eight (one hundred mg, 73.2 ol) in THF (1.35 mL). Following stirring for an additional 16 h at room temperature, a saturated aqueous NH4 Cl resolution (20 mL) was added. The aqueous layer was separated and extracted with Et2 O (three 20 mL). The combined organic phases have been dried over Na2 SO4 and concentrated in vacuo. The crude product.
