Procedure
Compound 56 neat (519.2 mg, 1.054 mmol) was cooled in an ice/water bath and sulfuryl chloride (128 μL, 1.58 mmol) was carefully added. The reaction mixture was allowed to warm to room temperature and was stirred overnight. After removal of the excess sulfuryl chloride in vacuo, the crude acid chloride 57 was used directly in the next step without further purification. 1HNMR (400 MHz, CDCl3): δ 1.35 (t, J=7.0, 12H), 1.86-2.06 (m, 4H), 2.28 (tt, J=23.8, 6.2, 1H), 2.45 (t, J=7.0, 2H), 4.14-4.24 (m, 8H), 5.82 (s, 2H). 31P NMR (162 MHz, CDCl3) δ 24.34 (s, 2P)
