Dimethylaluminium methaneselenolate (Me 2 AlSeMe, 1) acts as an acyl transfer agent for esterification. In cases of direct macrolactonisation (n = 10-12), this selenium-aluminium complex preferentially creates symmetric macrodiolides rather than macrolides. The factors determining macrodilactonisation were investigated and applied toward the total synthesis of norpyrenophorin, which result in a macrodilactonisation
二甲基硒化铝 (Me 2 AlSeMe, 1) 作为酯化的酰基转移剂。在直接大环内酯化(n = 10-12)的情况下,这种硒铝复合物优先产生对称的大二内酯而不是大环内酯。研究了决定大内酯化的因素并将其应用于去甲肾上腺素的全合成,这导致了 64% 的大内酯化产率。
