acids 7 (via 6-[(butylsulfanyl)methylene] and epoxide derivatives), one of which furnished hexalone derivative 11 (via an intermediate diazomethyl ketone derivative). The above-mentioned starting esters were converted to ethylene ketals, the free-radical oxidations of which led to hydrobenzofuran acids. One of the latter led to a hydrindanone (via a diazomethyl ketone), whose further chemical elaboration
将1-甲基-2-氧代环己烷甲酸乙酯(1a)及其同系物1b转化为氢异苯并呋喃酸7(通过6-[[(丁基硫烷基)亚甲基]和环氧化物衍生物),其中之一提供了己酮衍生物11(通过中间的重氮甲基酮衍生物) )。将上述起始酯转化为乙烯缩酮,其自由基氧化产生加氢苯并呋喃酸。后者之一导致了氢茚酮(通过重氮甲基酮),其进一步的化学精制产生了氢化可的松模型。第二次加氢苯并呋喃酸制得环丁烯酮(通过(重氮甲基酮),通过路易斯酸处理将其转化为更稳定的环戊烯酮异构体。
