Abstract
Rh(I) catalysed [2+2+2]-cyclotrimerisation of 1,6-diynes with monoynes in c ombination with stereospecific thermal or Ag(I) catalysed aldimine-->(metal lo) azomethine ylide-->cycloaddition cascades affords rapid access to compl ex heterocyclic benzene derivatives in one-pot processes with the generatio n 5 new bonds, 4 stereocentres and 3 rings.
