Unexpected Rearrangement in the Reaction of 7‐Mercapto‐4‐methylcoumarin with 1‐Mono‐ and 1,1‐Dimethyl Propargyl Alcohols Academic Article uri icon


  • The reaction of 7-mercapto-4-methylcoumarin (4) with 1-mono- and 1,1-dimethyl propargyl alcohols in H3PO4 afforded the corresponding β-(7-coumarinthio)ketones with a rearrangement of the carbon chain of propargyl. A possible mechanism of this rearrangement was proposed. Copyright © Taylor & Francis Group, LLC.
