We describe the first electrochemical activation of D–A cyclopropanes and D–A cyclobutanes leading after C(sp3)−C(sp3) cleavage to the formation of highly reactive radical cations. This concept is utilized to formally insert molecular oxygen af

A range of unprocessed, reducing sugar substrates (mono‐, di‐, and trisaccharides) is shown to take part in a straightforward four‐step synthetic route to water‐soluble, uncharged BODIPY derivatives with unimpaired chiral integrity and high f

We report the preparation of enantiomerically pure constrained geometry complexes (cgc) of the rare‐earth metals bearing a pentadienyl moiety (pdl) derived from the natural product (1R)‐(−)‐myrtenal. The potassium salt 1, [Kpdl*], was treated

Sigillins are highly chlorinated natural products from the springtail Ceratophysella sigillata (Collembola) that are used to deter arthropod predators. We report here the isolation and structure elucidation of sigillin F, a hydrogenated benzopyranone

The reaction of 1,2‐dipiperidinoacetylene (1) with 0.5 equivalents of SnCl2 or GeCl2⋅dioxane afforded the 1,2,3,4‐tetrapiperidino‐1,3‐cyclobutadiene tin and germanium dichloride complexes 2 a and 2 b, respectively. A competing redox reactio

A palladium-catalyzed intramolecular formal anti-carboamination of internal alkynes for the synthesis of tetrasubstituted enamines and pyrroles is reported. A broad range of different aniline derivatives, and also alkylated and benzylated amines, wer

P-Benzyl- and α-hydroxybenzyl-1,3-oxaphospholanes were synthesized by a one-step and a two-step acid catalyzed reaction of H2PCH2CH(R)OH (R = H, Me), respectively, with benzaldehyde. The latter is the first example of the access to a P-tertiary from
