Abstract

An asymmetric total synthesis of (-)-epibatidine (1), isolated from the skin of the Ecuadorian poison frog, Epipedobates tricolor, of the family Dendrobatidae, has been achieved by virtue of the development of asymmetric hetero Diels-Alder (DA) cycloaddition with an N- acylnitroso dienophile bearing the optically active 8-arylmenthol as a chiral source. Thus, in situ oxidation of the hydroxamic acid ent-12f incorporating the (1 S, 2 R, 5 S)-8-(2-naphthyl ...
