B-benzo[b]naphtho[2,3-d]furan-2-yl-boronic acid Chemical Properties,Usage,Production
Uses
B-benzo[b]naphtho[2,3-d]furan-2-yl-boronic acid can be used as organic synthesis intermediate and pharmaceutical intermediate, mainly used in laboratory research and development process and chemical production process.
Synthesis
12.6g of intermediate (A) and 500 mL of tetrahydrofuran (dehydrated) were put in a flask, and the resultant
was cooled to -78??C. 28 mL of n-BuLi (1.60M in hexane) was added, and stirring was conducted for 2 hours while
elevating the temperature to 0??C. Then, the solution was again cooled to -78??C, and 11.6g of B(OMe) 3 was added. After
stirring at 10 minutes at -78??C, stirring was further conducted for 5 hours while gradually elevating the temperature to
room temperature. After completion of the reaction, 1 N HCl aq. (100 mL) was added, and the reaction solution was stirred at room
temperature for 1 hour. Then, the solution was transferred to a separating funnel, and extracted with ethyl acetate. This solution was dried with MgSO 4, concentrated and washed with hexane, whereby 7.2g (yield: 65%) of white
solids of intermediate (B) were obtained.
