アブストラクト The high-yielding and highly enantioselective synthesis of carba[10]-[12]paracyclophanes I [X = (CH2)n; n = 7-9; R1 = Ts, 2-O2NC6H4SO2; R2 = MeO2C, HOCH2, n-Bu, MeCH(OH), etc.] has been achieved with up to 93% ee by the cationic rhodium(I)/(S,S)-bdpp-catalyzed [2 + 2 + 2] cycloaddn. of cyclic diynes II and terminal alkynes R2C竕｡CH under high substrate concns. [bdpp = 2,4-bis(diphenylphosphino)pentane]. [on SciFinder(R)]
