Sequentially Palladium-Catalyzed Processes in One-Pot Syntheses of Heterocycles
Applied Sciences, 2015 Sequentially Pd-catalyzed processes are excellent entries to heterocycle synthesis. The broad mechanistic variety combined with often very mild reaction conditions allow the concatenation of elementary organic and organometallic steps to novel sequences ...

Recent Advances in Organocatalyzed Domino C–C Bond-Forming Reactions
Molecules, 2017 Reactions that form a C–C bond make up a foundational pillar of synthetic organic chemistry. In addition, organocatalysis has emerged as an easy, environmentally-friendly way to promote this type of bond formation. Since around 2000, organocatalysts have

Synthesis of (–)-Indolizidine 167B based on domino hydroformylation/cyclization reactions
Beilstein Journal of Organic Chemistry, 2008 The synthesis of (–)-Indolizidine 167B has been achieved from optically active (R)-3-(pyrrol-1-yl)hex-1-ene. The key step is a highly regioselective hydroformylation reaction and a one-pot intramolecular cyclization providing a general approach to the ...
