Synthesis and structure determination of FR109615, a new antifungal antibiotic.
The structure of FR109615, a new antifungal antibiotic, was determined to be (1R,2S)-2-aminocyclopentane-1-carboxylic acid ((-)-cis-2-ACPC: 8a) by X-ray analysis. (-)-cis-2-ACPC (8a) was also synthesized via optical resolution of 3a and 3b derived from (+/-)-cis-2-ACPC hydrochloride (1). 8a showed potent antifungal activity, while its antipode (+)-cis-2-ACPC (8b) had no activity.
