The direct transformation of MOM-protected alcohols into the corresponding acetates by acetic anhydride/ferric chloride in CH2Cl2, in a one-step process and good to excellent yields, is reported. The reaction has been applied to a variety of substrates and occurs with retention of configuration.

A continuous process for efficiently co-producing secondary alcohols of long-chain olefins and lower carboxylic acid esters, comprising (I) performing an acid/olefin reaction in the presence of a heterogeneous catalyst such as Amberlyst 15, and (II) performing an ester-exchange reaction in the presence of, e.g., titanium alcoholate. A desirable feature of the process is the ability to produce co-products of choice.

(EN) The present invention relates to methods of inhibiting HIV-mediated cell killing which comprises inhibiting the interaction between the CS3 region and viral gp41 and its receptor on the surface of lymphocytes. The invention provides for methods which employ peptides, peptide derivatives, or antibodies to inhibit the CS3/CS3 receptor interaction. In addition, the invention also relates to the CS3 receptor. The present invention is based in part on the discovery that a CS3 specific cellular receptor is widely distributed on human lymphocytes and forms a 108 kd complex with CS3-HSA peptide conjugate. It was further discovered that CS3 peptide effectively blocks HIV mediated cell infection and killing. Therefore, the present invention provides for methods of treatment and prophylaxis of HIV infection as well as a means for better understanding the physiology of acquired immunodeficiency syndrome (AIDS).(FR) Procédés d'inhibition de la destruction de cellules due au VIH consistant à inhiber l'interaction entre la région CS3 de la glycoprotéine gp41 virale et son récepteur à la surface des lymphocytes. Les procédés proposés sont l'emploi de peptides, de dérivés peptidiques ou d'anticorps visant à inhiber l'interaction CS3/récepteur CS3. L'invention porte également sur le récepteur CS3. L'invention se fonde en partie sur la découverte qu'un récepteur cellulaire spécifique CS3 est largement réparti sur les lymphocytes humains et forme un complexe de 108 kd avec le conjugué peptidique CS3-HSA. On a aussi découvert que le peptide CS3 bloque effectivement l'infection et la destruction de cellules dues au VIH. En conséquence, on propose des procédés de traitement et de prophylaxie de l'infection par le VIH ainsi qu'un moyen de mieux comprendre la physiologie du syndrome d'immunodéficience acquise (SIDA).
