rearrangement. DFT calculations suggest that the effect is electronic although there is also a steric effect of the bulky silylgroup. This strategy for influencing the regiochemical outcome of the Claisen rearrangement was then employed in a shortsynthesis of the furo[2,3‐g]chromene, (−)‐pestalotheol D, that confirms the absolute stereochemistry of the natural product.
