The C19 diterpenoid alkaloids (C19 DTAs) are a large family of natural products, many of which modulate the activity of ion channels in vivo and are therefore of interest for the study of neurological and cardiovascular diseases. The complex architec

A Cr-photocatalyzed [4 + 2] cycloaddition between dienes and electron-deficient alkenes is reported, accessed by up to three converging pathways to yield the “meta” adducts.

A combined experimental and theoretical investigation aims to elucidate the necessary roles of oxygen in photoredox catalysis of radical cation based Diels-Alder cycloadditions mediated by the first-row transition metal complex [Cr(Ph2phen)3](3+), wh

A full account of our investigation of C–C bond migration in the cycloisomerization of oxygen-tethered 1,6-enynes is described. Under Pt(II) and/or Ir(I) catalysis, cyclic and acylic alkyl groups were found to undergo 1,2-shifts into metal carbenoi

Rhodium-catalyzed intramolecular carboacylation of alkenes, achieved using quinolinyl ketones containing tethered alkenes, proceeds via the activation and functionalization of a carbon-carbon single bond. This transformation has been demonstrated usi

A C-C bond migration event during the cycloisomerization of 1,6-enynes is described. Two different catalytic systems, iridium- or platinum-based, are able to induce this process. Alkyl migrations of larger rings and acyclic groups indicate that the r

Optimal reactivity for these cycloadditions is observed using near UV irradiation; visible-light promotion is effective too, albeit with lower yields.

C—C bond migration into metal carbenoid intermediates generated through the cycloisomerization of oxygen-tethered 1,6-enynes (I) and (III) is reported.
