    摘要: A new process prepares retiferol derivatives of formula I: wherein A is —C ≡C— or —CH═CH—, and R1 and R2 are independently of each other lower alkyl or lower perfluoroalkyl, one version couples ketones of formula 1I with compounds of formula III A second version couples phosphinoxides of formula IV with aldehydes of formula V. Compounds of formula I are useful in the treatment or prevention of hyperproliferative skin diseases and for reversing the conditions associated with photodamage.

    摘要: A process is disclosed for reducing amino acids and derivatives thereof Compounds of formula (I), in which n=0 or 1 and R.sup.1, R.sup.2, R.sup.3, R.sup.4, R.sup.5 and R.sup.6 have the meanings given in the description, are reduced to the corresponding amino alcohols of formula (II): the formula (I) compounds are converted in a first step, in at least one alcohol and with the addition of acid and heat to an ester, this process producing a reaction mixture containing the ester; the ester is converted in a second reaction step with alkali or alkaline earth borohydride to compounds of formula II. By specifying that the second step be carried out without isolating the ester from the reaction mixture and by using alkali or alkaline earth borohydrides which are not activated, the invention facilitates the production from amino acids and their derivatives of the correponding alcohols in a simple "single vessel" process, with high yields and in such a way as to preserve a given centre of chirality. Applications: synthesis components, preparation of optically active compounds splitting of racemic compounds. ##STR1##
