Abstract

In this article, a Lewis acid mediated 1,4โ€addition/formal [3+2] cycloaddition reaction engaging functionalized ฮฒโ€carboline and 1,4โ€benzoquinone has been demonstrated. Application of this developed technology facilitated the construction of the challenging Cโ€9โ€ฒโ€“Cโ€15 quaternary center linkage in the dimeric indole alkaloid, haplophytine, and enabled the preparation of an advanced key intermediate en route to the total synthesis of this historical natural product.

A synthetic pathway is presented to a functionalized pseudopeptide molecular platform for use in supramolecular and solution-phase combinatorial chemistry. The platform contains amino acids with quaternary asymmetric centers, the conยฎgurations of which are determined by the method of synthesis.
