Gold(I)‐Catalyzed Domino Cyclization for the Construction of Trispirocyclic Cyclohexanes

ChemistryEurope, EarlyView.
We describe herein a series of intricate trispirocyclic architectures that have been synthesized from readily available substrates through an operationally simple one‐pot transformation under mild conditions. An unprecedented gold(I)‐catalyzed domino cyclization involving 2‐ethynylbenzyl alcohol derivatives and heterocyclic α,β‐unsaturated imines ...

Intramolecular N···F Pnictogen Bond Mitigates the Explosive Behavior of Azido‐L‐Phenylalanines

ChemistryEurope, EarlyView.
An intramolecular N···F pnictogen bond is the key for the chemical stabilization of the fluorinated azido‐L‐phenylalanines, mitigating the risk of explosion and thus facilitating the handling and storage of these materials. Organic azides are versatile intermediates but are plagued by intrinsic instability and potential explosiveness. Here, it is shown

The Challenging P‐Alkylation of Aromatic Phosphorus Heterocycles and Follow‐Up Reactions

ChemistryEurope, EarlyView.
P‐alkylation of λ3σ2‐phosphinines is hindered by weak nucleophilicity and scarce synthetic access, previously requiring multistep routes or extreme electrophiles. A direct ambient‐condition method is reported using 3,5‐bis(trimethylsilyl)‐phosphinine/B(C6F5)3 with esters or iso(thio)cyanates to generate stable 1‐R‐phosphininium salts.
