A formal total synthesis of manzacidin B is described. β,β-Disubstituted γ-hydroxy-β-aminoalcohol, the key structure of manzacidin B, is stereoselectively constructed via sequential Henry reactions. By taking advantage of noncovalent interactions, such as intramolecular hydrogen bonding and chelation, we could diastereodivergently control the stereoselectivity of the Henry reaction.
描述了一种正式的全果酸B的合成。β,β-二取代的γ-羟基-β-氨基醇(甘露糖苷B的关键结构)是通过连续的亨利反应立体选择性地构建的。通过利用非共价相互作用,例如分子内氢键和螯合,我们可以非对映地控制亨利反应的立体选择性。
