Synthesis of the Antifungal Agent Neoenactin A and Its N-Deshydroxy Derivative
摘要:
The first total and unequivocal syntheses of neoenactin A (1, NE A) as well as its N-deshydroxy analog 2 are described. The two key steps in the syntheses were the oxidative cleavage of an appropriate olefin 8a to yield the desired keto acid 9 and the Michael addition of serinehydroxamates 11 or 12 to the appropriate vinyl ketone 10. Biological activity of 1 and 2 against Escherichia coli and several fungi has been investigated.
