The synthesis of new, highlysubstituted, and hindered 1‐hydroxyindole‐2‐carboxylates 1 is described. Substrates 2, prepared through a two‐step synthetic sequence, were treated with relatively weak nucleophiles in the presence of SnCl2 · 2H2O to afford compounds 1. In particular, nucleophiles of low reactivity and/or high steric hindrance reacted efficiently to give 1 in good to modest yields.

Synthesis of new 1‐hydroxyindole‐2‐carboxylates 1 and mechanistic studies on the reactionpathways were described. The substrates 2, prepared through two‐step synthetic sequences, were treated with nucleophiles in the presence of SnCl2 · 2H2O to obtain compounds 1. In particular, the mechanistic studies led to a significant finding that reactions with thiol nucleophiles occur through a newly proposed
