2-chloro-10-fluoro-8,9-dihydroxy-6H-benzofuro[3,2-c]chromen-6-one [ No CAS ]

Yield	Reaction Conditions	Operation in experiment
70%	With laccase; In aq. phosphate buffer; at 20℃; for 24h;pH 7.15;Enzymatic reaction;	General procedure: The laccase (Suberase?, 2.0mL) was added to a mixture of the catechol (2.0mmol), coumarin (2.0mmol) and phosphate buffer (20.0mL, 0.10M, pH 7.15) in a 250mL round bottom flask stirred under air at rt. More laccase (2.0mL) was added after 2, 18 and 20h. The mixture was vigorously stirred under air until the substrates were consumed as judged by TLC. The mixture was extracted with EtOAc and washed two times with water (20.0mL). The organic phases were then combined and the solvent evaporated. The residue, a powder, was purified by washing with EtOAc or by flash chromatography or recrystallization. The recrystallization was accomplished from a combination of MeOH and EtOAc. Products were characterized by 1H NMR, 13C NMR, and MS.
