Revisit to ()-Civetone Synthesis
Natural Product Communications, 2012 The synthesis of ( Z )-civetone ( 1 ) is described starting from oleic acid ( 5 ) via a series of reactions, intermolecular olefin self-metathesis, bromination/dehydrobromination into acetylene, semi-hydrogenation and intramolecular Dieckmann ...

The activation mechanism of Fe-based olefin metathesis catalysts
, 2014 Density functional theory calculations have been used to describe the first turnover for olefin metathesis reaction of a homogenous Fe-based catalyst bearing a N-heterocyclic carbene ligand with methoxyethene as a substrate.

Modular and Stereoselective Synthesis of Cyclobutane β‐Amino Alcohols
Angewandte Chemie, Volume 138, Issue 43, 19 October 2026.Late‐stage functionalization and photoisomerization of 1,2‐azaborine leads to a general strategy for the synthesis of diversely substituted cyclobutane β‐amino alcohols. The relative stereochemistry of the resulting products is unambiguously defined by the stereospecific and stereoselective nature of the photoisomerization‐hydrogenation‐oxidation ...

Synthetic Strategies for the Construction of Cyclobutane‐Fused Heterocycles
European Journal of Organic Chemistry, Volume 29, Issue 40, 27 October 2026.Cyclobutane‐fused heterocycles are important motifs commonly present in bioactive compounds, recognized for their rigid 3D structures that confer unique properties. However, synthesizing these compounds remains challenging. This review discusses current methods for their synthesis, such as photochemical, metal‐catalyzed, and Lewis acid‐mediated [2 + 2]

Synthesis of Medium-Sized Carbocycles by Gallium-Catalyzed Tandem Carbonyl-Olefin Metathesis/Transfer Hydrogenation [PDF]
, 2019 We report a catalytic tandem process involving a ring-closing carbonyl-olefin metathesis and a transfer hydrogenation. 1,4-Cyclohexadiene has been used as H2 surrogate to reduce the cyclic alkenes formed after the metathesis step. The same NHC-stabilized
