In situ generated bromonium-catalyzed and visible-light photocatalytic Achmatowicz rearrangements of furfuryl alcohols using cyclic diacyl peroxides as oxidants are described. Both protocols feature broad substrate scope, excellent functional group tolerance, and mild reaction conditions, affording the synthetically useful dihydropyranone derivatives in good yields.
描述了使用环状二酰基过氧化物作为氧化剂的糠醇的原位产生的溴催化的和可见光的光催化Achmatowicz重排糠醇。两种方案均具有广泛的底物范围,出色的官能团耐受性和温和的反应条件,从而以高收率提供了合成上有用的二氢吡喃酮衍生物。
