The first diastereoselective total synthesis of the bisindole alkaloid raputindole A is reported. After Au(I)-catalyzed assembly of the cyclopenta[f]indole tricycle, it was possible to hydrogenate the indene double bond regio- and diastereoselectively through iridium catalysis, guided by a preinstalled hydroxy function. Attempted HWE reaction led to formal elimination of formaldehyde from an α-quaternary
报道了双吲哚生物碱拉普吲哚A的第一个非对映选择性全合成。在Au(I)催化的环戊[ f ]吲哚三环的组装后,可以在预先安装的羟基官能团的引导下,通过铱催化将茚双键区域和非对映选择性地氢化。尝试的HWE反应导致从α-季环戊烷甲醛中甲醛的正式消除,而Takai烯烃化可避免甲醛的发生。在Suzuki-Miyaura交叉偶联和脱保护/氧化后,以13个线性步骤获得了(±)-raputindole A,总产率为18%。

tertiary propargylicalcohol precursors. However, none of the enones underwent the desired Nazarov cyclization to a cyclopenta[f]indole. More suitable were 6-hydroxyallylated indolines which gave good yields of cyclopenta[f]indolines after treatment with SnCl4, as soon as sterically demanding beta-cyclocitral adducts were reacted. Most successful were Pt(II) and Au(I)-catalyzedcyclizations of N-TIPS-protected
