One-Step Tethering of ω-Mercaptoalkyl Function to Alcohols

Abstract A new method of attachment of ω-mercaptoalkyl function to primary, secondary, and tertiary hydroxy groups based on ω-mercaptoalkyl monomalonates is reported. The attachment process proceeds in one stage and does not require a deprotection step thus directly providing high yields of unsymmetric malonates possessing a terminal thiol functionality.
