Abstract

We have developed an efficient cascade reaction, a Suzuki-Miyaura coupling followed by an aldol condensation, for the construction of phenanthrene derivatives using microwave irradiation. For example, the reaction of methyl 2-bromophenylacetamide with 2- formylphenylboronic acid in the presence of a palladium catalyst and a base provided a biaryl intermediate, which underwent in situ cyclization to afford the corresponding ...
