Palladium catalysed bis- and tris-cyclisations furnishing fused cyclopropyl carbo/heterocycles
摘要:
Catalytic bis- and tris-cyclisation of a series of acyclic carbo- and heterocyclic precursors results in formation of two or three rings, two or three C-C bonds and two asymmetric tetrasubstituted C-centres regio- and stereoselectively in excellent yield. (c) 2006 Elsevier Ltd. All rights reserved.
