摘要:The Syntheses Of (-)-Furodysin ((-)-2A) And (-)-Furodysinin ((-)-3A) In Four Steps Starting From (+)-9-Bromocamphor (18) Has Been Accomplished,Thus Establishing The Absolute Configuration Of These And Related Metabolites. This Was Made Possible By The Unexpected Exo Selectivity In The Aldol Condensation Of Camphor-Like Enolates With Aldehydes. This Has Been Found To Be A General Phenomenon In The Camphor System. Further,Anionic Fragmentation Of The C1-C7 Bond Of Camphor Derivatives Has Allowed Access To Synthetic Intermediates Containing Functionalized Six-Membered Rings,Thus Opening Up Avenues From Camphor To A New Class Of Chiral Pool Elements Not Currently Available From Chiral Pool Substances.
