Visible-Light-Promoted Oxo-Sulfonylation of Ynamides with Sulfonic Acids

A visible-light-promoted oxo-sulfonylation of ynamides with sulfonic acids 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 comprised the merits of this synthetic transformation.

Copper-catalyzed domino route to natural nostoclides and analogues: A total synthesis of nostoclides i and II

An original and convenient domino route to natural nostoclides I and II has been developed using a two-step sequence consisting of a copper-cat-alyzed tandem reaction associated with Suzuki cross-coupling. The methodology employed for this total synthesis appeared to be an interesting and suffi-ciently flexible tool to allow the synthesis of numer-ous analogues of these nostoclides.
