Two strategies are described en route to an enantioselective total synthesis of gelsenicine. One approach centers on a chirality transfer cycloisomerization that ultimately fell short. Separately, an asymmetric catalysis route utilizing bisphosphine-

A direct dearomative photocatalyzed (3+2) cycloaddition between indoles and vinyldiazo reagents is described. The transformation is enabled by the development of a novel oxidizing Cr

A synthesis of a δ-ketohydroperoxide is described, addressing potential functional-group compatibilities in these elusive species relevant to combustion and atmospheric chemistries. The hydroperoxide is installed via sulfonylhydrazine substitution,

The steric and electronic drivers of regioselectivity in platinum-catalyzed intramolecular hydroalkoxylation are elucidated. A branch point is found that divides the process between 5-exo and 6-endo selective processes, and enol ethers can be accesse

The first total synthesis of (±)-gelsenicine is described. The strategy centers on a pivotal metal-catalyzed cycloisomerization–Cope rearrangement sequence to construct the central core of the Gelsemium alkaloid. The study provided a stimulating f

A direct (3+2) cycloaddition between alkenes and vinyl diazo reagents using Cr or Ru photocatalysis is described. The intermediacy of a radical cation species enables a nucleophilic interception by vinyl diazo compounds, a departure from their tradit

A synthetic approach to pordamacrine A that features two key transformations is discussed. The first transformation applies an Ireland-Claisen rearrangement to establish sterically congested vicinal carbon centers. Although a hard enolization techniq
