Diazo decomposition of trans,trans-farnesyl diazoacetate catalyzed by dirhodium(II) tetraacetate, Rh2(OAc)4, resulted in the formation of the 13-membered ring macrolide cyclopropane-fused lactones, (1α,13β)- and (1α,13α)-6,10,14,14-tetramethyl-(E),(E)-3-oxabicyclo[11.1.0]tetradeca-5,9-dien-2-one I, in good yield by intramol. cyclopropanation of the terminal double bond. Use of dirhodium(II) carboxamidate catalysts led to the exclusive formation of the product II from intramol. cyclopropanation of the allylic double bond. The influence of catalyst ligand on this distribution of products has been determined Similar results for intramol. cyclopropanation were obtained with (-)-(7R)-6,7-dihydrofarnesyl diazoacetate and cis-nerolidyl diazoacetate, both of which yielded macrolide cyclopropane-fused lactones with dirhodium(II) carboxylates but underwent cyclopropanation of the allylic double bond with use of dirhodium(II) carboxamidates. With neryl diazoacetate use of dirhodium(II) perfluorobutyrte, Rh2(pfb)4, gave the 11-membered macrolide product from C-H insertion into an allylic Me group at C(8) in high yield and without evidence of intramol. cyclopropanation.
