Synthesis of a diastereoisomer of the C-15 ∼ C-26 segment of amphidinolide L
Abstract
In order to determine the absolute stereochemistry of amphidinolide L 1, a cytotoxic macrolide from a marine dinoflagellate, (16R, 18S, 20R, 22S, 23R, and 25R)-2, one of the eight possible diastereoisomers of the C(15)–C(26) segment has been synthesized, thus providing an authentic sample for degradation studies of 1.
