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 12 S ,13 R ,18 R.
