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.
一种新的工艺制备了公式I的视黄醇衍生物:其中A为—C≡C—或—CH2CH—,而R1和R2分别独立地为较低的烷基或较低的全氟烷基,其中一种版本将公式1I的酮与公式IIIA的化合物偶联,另一种版本将公式IV的膦氧化物与公式V的醛偶联。公式I的化合物在治疗或预防皮肤过度增生性疾病以及逆转与光损伤相关的病症方面是有用的。
