The past decades have witnessed the great progress of transition metal catalyzed C-H and C-C activations.[1] Compare to the extensively reported C-H activations, the C-C activations have been less reported.Recently, Cramer and co-workers reported a very interesting Rh-catalyzed C-C/C-H activation of the tert-cyclobutanols.As shown in Figure 1, in the presence of the Rh(Ⅰ) catalyst (3) and the difluorphos ligand (L), the aryl substituted cyclobutanols substrates (1) can efficiently transform to the indanol products (2) within 12 hours.In addition to the high yields, the observed high enantio-and diastereoselectivity in Cramers reaction greatly intrigued us.
