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:
The present invention relates to a new method for making compounds of formula ##STR1## and intermediates for making compounds of formual II. The compounds of this invention are useful intermediates for the manufacture of pharmacologically active compounds suitable for the treatment of viral infections, particularly, those caused by HIV and other retroviruses.
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##
摘要:
The invention relates to a process for the preparation of N-tert.butyl-decahydro-2-[2(R)-hydroxy-4-phenyl-3(S)-phthalimidobutyl]-(4aS,8aS)-isoquinoline-3(S)-carboxamide of the formula ##STR1## as well as novel intermediates. The compound of formula I is a valuable intermediate for pharmacologically active compounds. The compound of formula I can be converted into pharmacologically active compounds which are suitable for the treatment of viral infections, such as those caused by HIV and other retroviruses.
摘要:
The invention relates to intermediate compounds which are useful in the preparation of N-tert-butyl-decahydro-2- 2 (R)-hydroxy-4-phenyl-3(S)-phthalimidobutyl!-(4aS, 8aS)-isoquinoline-3(S)-carboxamide. The final products are suitable for the treatment of vital infections, such as those caused by HIV and other retroviruses.
摘要:
The present invention provides compounds of formula I having BACE1 and/or BACE2 inhibitory activity, their manufacture, pharmaceutical compositions containing them and their use as therapeutically active substances. The active compounds of the present invention are useful in the therapeutic and/or prophylactic treatment of e.g. Alzheimer's disease and type 2 diabetes. The invention further provides a radio-labelled derivative thereof.
