A formaltotalsynthesis of (−)-aspidophytine (2), a key substructure associated with the heterodimeric indole alkaloid haplophytine (1) and itself a natural product, has been established by employing the homochiral and enzymatically derived cis-1,2-dihydrocatechol 8 as a starting material. Specifically, compound 8 has been converted into the pentacyclic product 26, an advanced intermediate associated
