Synthetic detective work: FR252921, an unusual 19-membered lactone-dilactam, and three of its diastereomers were prepared by a versatile, convergent strategy from three key segments (see scheme). Comparison of the synthetic compounds with natural material established conclusively that FR252921 has the configuration 12S,13R,18R.
