Yield:629-03-8 97%
Reaction Conditions:
with N-Bromosuccinimide;triphenylphosphine in dichloromethane at -78 - 20; for 12 h;Darkness;chemoselective reaction;
Steps:
Dibromination of Diols 9 to 1,4-Dibromo Compounds 11
General procedure: NBS (534 mg, 3 mmol) was dissolved in CH2Cl2 (10 mL) contained in a 50 mL flask. Ph3P (786 mg, 3 mmol) and 9 (1 mmol) were added sequentially dropwise into the NBS solution at -78 °C. The reaction mixture was stirred in the dark at r.t. for 12 h and the progression of the reaction was monitored by TLC (eluent: PE-EtOAc, 20:1). The mixture was then concentrated in vacuo and the product 11 was isolatedby flash chromatography on a silica gel column (eluent: PE-EtOAc, 30:1).
