Chemical Structure from Scientific Research

Reaction conditions a as shown in Table 1 . b DPS (1.2 equiv) and Bu 4 NHSO 4 (2.0 equiv) were used in reaction conditions b. c NMR yields were determined by using CH 2 Br 2 as an internal standard. d Na 2 S 2 O 7 (2.0 equiv) and Bu 4 NHSO 4 (1.1 equiv) were used. Note: The liquid DMS and DPS are volatile and toxic. Exercise extreme caution when handling the liquid. DPS, diisopropyl sulfate.
