Development of Domino Reactions Based on Skeletal Rearrangement

YAKUGAKU ZASSHI, 2011
Domino reactions, which enable formations of several chemical bonds and multi-step transformation in one-pot process, have received much attention as an efficient synthetic methodology to preserve chemists from time-consuming purification protocols and protection-deprotection procedures.

Post-Ugi gold-catalyzed diastereoselective domino cyclization for the synthesis of diversely substituted spiroindolines

Beilstein Journal of Organic Chemistry, 2013
An Ugi four-component reaction of propargylamine with 3-formylindole and various acids and isonitriles produces adducts which are subjected to a cationic gold-catalyzed diastereoselective domino cyclization to furnish diversely substituted spiroindolines.

Enantioselective Heck/Tsuji−Trost reaction of flexible vinylic halides with 1,3-dienes

Nature Communications
The enantioselective domino Heck/cross-coupling has emerged as a powerful tool in modern chemical synthesis for decades. Despite significant progress in relative rigid skeleton substrates, the implementation of asymmetric Heck/cross-coupling cascades of ...

2,3‐Epoxyamide‐alcohols in Domino Reactions: En Route to Molecular Diversity

ChemistryOpen
The synthesis of polycyclic γ‐ and δ‐lactams bearing up to four contiguous fully controlled stereocenters is presented. For that purpose, we developed an original approach based on the use of 2,3‐epoxyamides in domino reactions by taking advantage of the
