Metathesis Reactions of Carbohydrates: Recent Highlights in Cross‐Metathesis
European Journal of Organic Chemistry, 2010 AbstractMetathetical processes play a prominent role in the development of useful transformations because of their mildness, tolerance of functional groups, and synthetic potential. On the other hand, carbohydrates have gained well‐deserved relevance in the study of biological processes.

Synergistic approach to polycycles through Suzuki–Miyaura cross coupling and metathesis as key steps
Beilstein Journal of Organic Chemistry, 2018 This account provides an overview of recent work, including our own contribution dealing with Suzuki–Miyaura cross coupling in combination with metathesis (or vice-versa). Several cyclophanes, polycycles, macrocycles, spirocycles, stilbenes, biaryls, and

Conversion of butanol to propene in flow: A triple dehydration, isomerisation and metathesis cascade
Catalysis Communications, 2022 A combined three-step flow cascade conversion of n-butanol to propene is demonstrated. Zeolite H-ZSM-5 gives high conversion in the initial n-butanol dehydration step (98%).
