A Strategy To Obtain o-Naphthoquinone Methides: Ag(I)-Catalyzed Cyclization of Enynones for the Synthesis of Benzo[ h]chromanes and Naphthopyryliums
Wu, Feng,Zhu, Shifa
, (2019)
A new strategy to obtain o-NQM intermediates through a ring-formation strategy by Ag(I)-catalyzed cyclization of 2-alkenylphenyl alkynyl ketones and its [4 + 2] annulations with styrenes has been developed. This reaction features high efficiency, mild reaction conditions, as well as flexible substitutions and atom economy. The obtained benzo[h]chromane products were further oxidized to naphthopyryliums, which displayed tunable photophysical properties.
An efficient three-component one-pot approach to the synthesis of 2,3,4,5-tetrahydro-1H-2-benzazepines by means of rhodium-catalyzed hydroaminomethylation

We have developed a novel and efficient three-component one-pot, catalytic approach for the synthesis of 2,3,4,5-tetrahydro-1H-2-benzazepines, using a rhodium catalyst that does not require phosphine. The isolated yields are excellent and the protocol tol
