European Journal of Organic Chemistry, EarlyView.Isotelluroureas allow for the use of alkynoates for asymmetric (4+2)‐heterocycloadditions with different Michael acceptors. Alk‐2‐ynoates are readily available starting materials which, in principle, can be utilized for cycloadditions in analogy to structurally similar allenoates.

Catalytic Strategies for Amide-Based Michael Additions: Advances and Perspectives
Journal of ChemistryThe Michael addition is a cornerstone transformation in organic synthesis, enabling efficient C–C and C–heteroatom bond formation. Traditionally, α,β-unsaturated carbonyl compounds such as enones and esters have dominated as Michael acceptors, whereas α ...

European Journal of Organic Chemistry, EarlyView.We present a rapid, operationally simple, and broadly applicable protocol for the catalytic formation and in situ electrochemical characterization of chiral a,b‐unsaturated iminium ions by cyclic voltammetry (CV). Using only 5 mol% of the aminocatalyst, we systematically measure the reduction potential of over 50 iminium intermediates, revealing how ...

European Journal of Organic Chemistry, EarlyView.The allenyl ketone products of an enol ether formation–propargyl Claisen rearrangement sequence are susceptible to acid‐catalyzed isomerization to yield the corresponding conjugated dienones. A diaryl thiourea catalyst was found to promote the desired reaction sequence while suppressing the competing isomerization.
