We report here a novel reductive coupling reaction of conjugated, non- or poorly enolizable aldehydes induced by H(2) S and operative in aqueous solutions under prebiotically relevant conditions. This reaction leads from retinal to β-carotene, and from benzylic aldehydes to the corresponding diarylethylenes. This novel reaction also opens a new potentially prebiotic pathway leading from glyoxylic acid
我们在这里报告了由H(2)S诱导和水溶液在益生元相关条件下有效的共轭,非或难烯化醛的新型还原性偶联反应。该反应从视网膜到β-胡萝卜素,从苄基醛到相应的二芳基乙烯。这种新颖的反应还开启了一条新的潜在的益生元途径,从乙醛酸到还原性三羧酸循环中涉及的各种化合物。益生元感兴趣的这种C-C键形成反应可能在热液喷口的富含硫化物的环境中有效,据推测这是有机化学进化第一步的可能场所。
