Abstract
A method was developed for the preparation of macrocyclic 2-alkylcycloalkanones by alkylation of 2-carbethoxy-α-cyclothienones with subsequent desulfurization and ketone cleavage. Only C-alkylation occurs under the described conditions (potassium metal in hexamethylphosphoric triamide, sodium hydride in dioxane).
