Isolation and structure determination of (+)-trienomycin F. An endgame synthetic strategy for the trienomycin family of antitumor antibiotics
摘要:
A new trienomycin antibiotic, (+)-trienomycin F (4), has been isolated and characterized. The structure was elucidated via spectroscopic comparison with semisynthetic 4 prepared from (+)-trienomycinol (5). The latter sequence implemented an endgame synthetic strategy designed to furnish the trienomycin family of antibiotics from a common advanced intermediate [i.e., macrocycle (+)-5].
