Procedure
Sulfuryl chloride (687 μL, 8.49 mmol) was added drop-wise to 61 (2.03 g, 4.24 mmol). The neat reaction was stirred at room temperature for 2.5 hr. The excess sulfuryl chloride was removed under reduced pressure resulting in chloroformate 62 (1.87 g, 97%) that was used without purification. 1H NMR (400 MHz, CDCl3): δ 1.35 (t, J=7.1, 12H), 2.17-2.36 (m, 2H), 2.53 (tt, J=23.8, 6.5, 1H), 2.80 (t, J=7.5, 2H), 4.15-4.24 (m, 8H), 5.82 (s, 2H). 31P NMR (162 MHz, CDCl3) δ 23.72 (s, 2P).
