rearrangement of the indole to form a spirooxindole. Synthetically, formation of the oxindole ring was stereoselectively accomplished by reaction of the appropriate indole precursor with N-bromosuccinimide. For optimum results, the oxidation should be carried out prior to diketopiperazine cyclization. In this manner, we have synthesized the tetrahydro- and dihydro- analogues of spirotryprostatin B in four steps
