Versuchsvorschrift
According to the procedure described in Example 1(a) for the preparation of 3-biphenyl-4-yl-2,5-dihydro-2,5-dimethoxyfuran, 3-phenylfuran (see Pridgen, L. N.; Jones, S. S. J. Org. Chem. 1982, 47, 1590-1592 and Yang, Y.; Wong, H. N. C. Tetrahedron 1994, 32, 9583-9608; 848 mg, 5.89 mmol) provided 1.00 g (82%) of 2,5-dihydro-2,5-dimethoxy-3-phenylfuran as a yellow oil, which was an approximately 80:20 mixture of diastereomers by 1H NMR and used without further purification.
