Macrosphelides C and F were synthesized by lactonization of 14-oxo seco acids at the O(10)-C(11) bond followed by reduction and Mitsunobu inversion of the resulting hydroxyl group. The seco acids were prepared from the corresponding furans by furan ring-opening with NBS followed by further oxidation of the 4-oxo-2-alkenals with NaClO2. (C) 2001 Elsevier Science Ltd.

Baker's yeast reduction of ethyl acetoacetate provided in good yield ethyl 2(S)-hydroxybutanoate. The hydrolysis of the ester function after protection of the hydroxyl yielded an acid which, under BARTON'S free radical decarboxylation conditions, produced a free radical chiron of 2(S)-hydroxypropyl moiety; according to the reaction medium various chiral products from reaction of this entity were produced
