Δ2,6-Hexalin-1,5-dione (I) has been prepared from decalin-1,5-dione (III) as follows. The latter substance was converted to the diketal IX(R1 R2 H) which, on bromination with phenyl-trimethylammonium tribromide in tetrahydrofuran, was transformed into the 2,6-dibromo compound IX(R1 R2 Br). Treatment with potassium t-butoxide in t-butyl alcohol gave the diene diketal X, and this substance on
Δ 2,6 -Hexalin -1,5-二酮(I)已经从如下萘烷-1,5-二酮(III)制备。后者物质转化成缩酮IX(R 1 - [R 2 2H),其在与溴化苯基三甲基铵三溴化物在四氢呋喃中,转化到2,6-二溴化合物IX(R 1 - [R 2 溴) 。用叔丁醇钾在叔丁醇中的处理得到二烯二缩酮X,该物质经弱酸水解后转化为高度结晶的二烯二酮I。
