AbstractAn original and convenient domino route to natural nostoclides I and II has been developed using a two‐step sequence consisting of a copper‐catalyzed tandem reaction associated with Suzuki cross‐coupling. The methodology employed for this total synthesis appeared to be an interesting and sufficiently flexible tool to allow the synthesis of numerous analogues of these nostoclides.magnified image

A visible-light-promoted oxo-sulfonylation of ynamides with sulfonicacids is reported, giving rise to a collection of functionalized α-sulfonylated amides in a straightforward manner. The reaction proceeds sequentially through a cascade of electrophilic addition and photoinduced sulfonyl radical-sustained skeleton rearrangement. The high atom economy, mild reaction conditions, and wide substrate scope
