合成路线1
该中间体在本合成路线中的序号:(VIII)In a different procedure, biaryl formation via ortho palladation of diaryl ether (VII) provided the desired dibenzofuran (VIII) along with a small amount of regioisomer (IX). Kinetic resolution with alcalase produced the S-carboxylic acid (V), whereas the R-ester (X) was recycled by base-catalyzed epimerization.
