The oxidation of α-vinylallenic alcohols 3 with t-butyl hydroperoxide in the presence of catalytic amounts of vanadyl acetylacetonate, yields the epoxides 6 or, mainly, the cyclopentenones 5 depending on the secondary or tertiary class of the alcoholic function. In the same conditions, the vinylallenic alcohols 4 lead only to cyclopentenones 7.
在催化量的乙酰丙酮氧钒的存在下,用叔丁基氢过氧化物氧化α-乙烯基烯醇3可产生环氧化物6,或主要是环戊烯酮5,这取决于醇官能团的仲级或叔级。在相同条件下,乙烯基烯醇4仅导致环戊烯酮7。
