M. Ojika et al., STUDIES ON THE STEREOCHEMISTRY OF APLYRONINE-A - DETERMINATION OF THESTEREOCHEMISTRY OF THE C21-C34 FRAGMENT, Tetrahedron letters, 34(52), 1993, pp. 8505-8508
The absolute stereochemistry of the C21-C34 fragment 2 of aplyronine A
(1), a potent antitumor substance of marine origin, was determined by
the enantioselective synthesis.
