A new process prepares retiferol derivatives of formula I:
1
wherein
A is —C≡C— or —CH═CH—, and
R
1
and R
2
are independently of each other lower alkyl or lower perfluoroalkyl,
one version couples ketones of formula II 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:1的视黄醇衍生物:
其中A为—C≡C—或—CH═CH—,且R1和R2分别为较低的烷基或较低的全氟烷基,其中一个版本将公式II的酮与公式III的化合物偶联,另一个版本将公式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状况方面有用。
