AbstractÐIn an effort to prepare new ¯uorine-containing molecules as analogues of Plant Growth Regulators (PGRs), the indirect electrochemical reduction, by means of an aromatic anion mediator, of per¯uoroalkyl halides in the presence of purine and indolyl anions was carried out. The corresponding C

The cyclic analogue rac-14b of JH-I11 and its 22 isomer roc-14a were obtained by a multi-step synthesis starting from rac-a-terpineol. The Wadsworth-Emmons reaction was applied to the formation of the carbon chain and to the introduction of the ester function (esters 8a, b and 13% b). Morphogenetic
lowed by a spontaneous change in its surface properties, could also account for some of the change observed following irradiation of chlorpromazine. The sulfoxide, at these concentration levels, would not be expected to contribute to this change. Since all of these compounds are metabolites of chlo
