Fig. 3: Possible stereodivergence and chiral induction modes in enantioselective insertion of bulky alkynes.
From: Rhodium-catalyzed enantioselective and diastereodivergent access to diaxially chiral heterocycles
a Our previous studies of Rh-catalyzed coupling of 1-alkynylnaphthalenes and arenes in [4 + 2] and [3 + 2] annulation. b Possible stereochemistry control via different orientations of the arene and alkyne. c Possible stereochemistry control via participation of additional metal.
