Domino Constructions of Pentacyclic Indeno[2,1-c]quinolines and Pyrano[4,3-b]oxepines by [4+1]/[3+2+1]/[5+1] and [4+3] Multiple Cyclizations

New three‐component domino reactions have been discovered. The reactions are easy to perform (see scheme; MW=microwave irradiation) and proceed with fast rates, which makes work‐up convenient. Most of the multiple stereocenters and the geometry are controlled well. The stereochemistry has been unequ...

Description
Summary:New three‐component domino reactions have been discovered. The reactions are easy to perform (see scheme; MW=microwave irradiation) and proceed with fast rates, which makes work‐up convenient. Most of the multiple stereocenters and the geometry are controlled well. The stereochemistry has been unequivocally determined by X‐ray structural analysis.
