Biomass-based diols have been synthesized by a Zn/Bi-mediated Barbier-type of reaction from furanic aldehydes and allyl halides to access allylated diols. The allylated diols can be readily converted into alkylated diols by hydrogenation. These furanic diols could be potential replacements for fossil fuel based bisphenol A (BPA) which has an adverse endocrine-disrupting effect on humans. This mild
通过锌/铋介导的巴比尔型反应,从呋喃醛和烯丙基卤化物合成基于生物质的二醇,以获得烯丙基化的二醇。烯丙基化的二醇可以通过氢化容易地转化为烷基化的二醇。这些呋喃二醇可能是基于化石燃料的双酚 A (BPA) 的潜在替代品,双酚 A 对人类具有不利的内分泌干扰作用。这种温和且绿色的方案可提供高产率的对称和非对称二醇。烯丙基双键的化学选择性还原为二醇提供了独特的取代。
