Synthetic strategy toward ineleganolide: A cautionary tale

Abstract

We present a case study to demonstrate how complex molecule synthesis can benefit from quantum mechanics (QM) calculations. Theory is applied in two contexts: testing the chemical intuition used in retrosynthetic planning, along with expediting the resolution of unexpected challenges encountered during the course of the synthesis. From a computational lens, we examine retrospectively the strategies employed and the decisions made during our synthetic efforts toward the diterpenoid natural product ineleganolide. Seemingly logical and robust hypotheses are found to be ill-fated after theoretical investigation. Prior knowledge of these issues may have potentially saved valuable time and resources during our synthetic efforts. This cautionary tale suggests that synthetic campaigns can benefit from computational evaluation of synthetic plans.
