employed to introduce the elements of a butanone or pentanone side-chain as a prelude to adding a fused six-membered ring, thereby completing the preparation of several analogues of the Wieland-Miescher ketone 4a in which the angular substituent was oxygenated.
通过金属氨溶液还原一系列甲氧基苯甲酸和酯,然后将得到的1,4-二氢产物原位烷基化或分离并随后烷基化。三种不同类型的烷基碘被用来引入丁酮或戊酮侧链的元素,作为添加稠合六元环的前奏,从而完成了Wieland-Miescher酮4a的几种类似物的制备,其中角取代基被充氧了。
