Various C19 analogues of retinoic acid have been prepared from isopropyl t-butyl ketone. Potassium hydrogen sulphate in dimethyl sulphoxide proved an effective reagent for the elimination of water from intermediate hydroxyderivatives, but dehydration of 9-hydroxy-6,10-dimethyl-9-t-butylundeca-3,5,7-trien-2-one yielded 2-methyl-5-(4-isopropyl-1,5,5-trimethylhexa-1,3-dienyl)furan and 9-isopropyl-6,9
由异丙基叔丁基酮制备了各种视黄酸的C 19类似物。硫酸氢钾在二甲基亚砜中被证明是一种有效的试剂,用于从中间体羟基衍生物中消除水,但是脱水后生成的9-羟基-6,10-二甲基-9-叔丁基不饱和醇-3,5,7-三烯-2-酮2-甲基-5-(4-异丙基-1,5,5-三甲基六-1,3-二烯基)呋喃和9-异丙基-6,9,10-三甲基不饱和糖-3,5,7,10-丁烯-2 -一。
