[reaction: see text] Synthesis of a novel class of C-10 halogenated and C-12 oxygenated prostaglandin-A(2) derivatives (6a-6c) has been accomplished. (15S)-Prostaglandin-A(2) (1), from the gorgonian Plexaura homomalla, served as the starting material for the synthesis. The absolute configuration was determined using NMR.

The interesting bronchodilator activity of l-11-deoxy-11 alpha-[(2-hydroxyethyl)thio]prostaglandin E2 methylester (3a) is described. The preparation of 3a and its analogues by Michael-type additions to various members of the PGA series or by totalsynthesis using the lithiocuprate conjugate addition process is also described. Structure-activity relationships in this series are discussed.
An original approach for the synthesis from PGA2 of C-10 substituted PGE2 analogues is reported. A remarkable regio- and cyclo-selective Baeyer–Villiger reaction is described.

Prostaglandin A2-AcMe (1) and ProstaglandinA2 (2) were isolated from the octocoral Plexaurahomomalla and three semisynthetic derivatives (3-5) were then obtained using a reduction protocol. All compounds were identified through one- and two-dimensional (1D and 2D) nuclear magnetic resonance (NMR) experiments. Additionally, evaluation of in vitro cytotoxic activity against the breast (MDA-MB-213)
