A two-step synthesis of 6-alkyl-4-hydroxymethyl-3-chromene (6-alkyl-4-hydroxymethyl-2H-1-benzopyran) from addition of phenyl vinyl sulfoxide carbanion to 5′-alkyl-2′-hydroxyacetophenone is described. Application to the synthesis of 4-methyl-3-chromene (4-methyl-2H-1-benzopyran) and 4,4-dimethylchroman (3,4-dihydro-4,4-dimethyl-2H-1-benzopyran) is also presented.
描述了将苯基乙烯基亚砜碳酰离子加到 5′-烷基-2′-羟基苯乙酮上,分两步合成 6-烷基-4-羟甲基-3-苯并吡喃(6-alkyl-4-hydroxymethyl-2H-1-benzopyran)。 此外,还介绍了在合成 4-甲基-3-色烯(4-甲基-2H-1-苯并吡喃)和 4,4-二甲基-3-色烯(3,4-二氢-4,4-二甲基-2H-1-苯并吡喃)中的应用。
