A new efficient route to 7-ketocamphene, involving as the key-step, a solvolytic-type rearrangement of 3,3-ethylenedioxyisoborneol (via tosylate) is described. A side-reaction arising from acid-catalyzed fragmentation of 7,7-ethylenedioxycamphene was encountered and has been investigated further. A Baeyer-Villiger type oxidation with dioxane hydroperoxides in the presence of an acid has been noted
描述了一种新的有效途径,以7-酮庚烯为关键步骤,涉及溶剂化型3,3-乙二氧基异冰片醇(通过甲苯磺酸酯)的重排。遇到了由酸催化的7,7-乙撑二氧camp烯裂解产生的副反应,并已进行了进一步研究。已经注意到在酸存在下用二恶烷氢过氧化物的Baeyer-Villiger型氧化。
