WebJan 2, 2024 · Going for a ′SPIN′: The enantioselective synthesis of a series of 3,3′-diarylated 1,1′-spirobiindane-7,7′-diols (3,3′-diaryl-SPINOLs) was developed using a sequential Rh-catalyzed twofold asymmetric conjugate arylation/BF 3 -promoted diastereoselective spirocyclization. WebThe first transition-metal-free regioselective synthesis of 2,3-diarylindenones via tandem annulation of 2-alkynylbenzaldehydes with phenols is described. Two different modes of reaction controlled by electronic effects and temperature furnished either “non-rearranged” or “rearranged” indenones in high selectivity.
