give the corresponding 6H-benzo[c]chromen-6-ones and their 7,8,9,10-tetrahydro analogues, respectively, in 50–72% yields. Aryl 3-bromoacrylates are also converted into 2H-chromen-2-ones under the employed conditions.
在K 2 CO 3的存在下,在二甲基甲酰胺中通过微波辐照,将2-溴苯甲酸芳酯和2-溴环己-1-芳烷基芳酯环化,得到相应的6 H-苯并[ c ] chromen-6-one及其7,8, 9,10-四氢类似物,产率分别为50-72%。在所采用的条件下,将3-溴丙烯酸芳基酯也转化为2 H-铬-2-基。
(1-Benzylindole-3-yl)alkanoic Acids; Novel Nonsteroidal Inhibitors of Steroid 5.ALPHA.-Reductase (I).
A novel series of indole-3-alkanoic acids with varied N-benzyl substituents were synthesized as nonsteroidalinhibitors of steroid 5 alpha-reductase. The structure-activity relationships in this series were studied and the optimum carboxylic acid side chain was butyric acid. Furthermore, compounds with a diaryl substituent at the 1-position of the indole ring displayed strong inhibitory activities
