Versuchsvorschrift
For example, 4-pentenoic acid or an ester thereof yields γ-hydroxymethyl-γ-butyrolactone (5-hydroxymethyldihydrofuran-2-one) in a high yield. Cyclopentene-3-acetic acid yields 2,3-dihydroxycyclopentaneacetic acid γ-lactone, and 5-norbornene-2-carboxylic acid yields 5,6-dihydroxybicyclo[2.2.1]octane-2-carboxylic acid γ-lactone (5-hydroxy-2,6-norbornanecarbolactone=5-hydroxy-3-oxatricyclo[4.2. 1.04,8]nonan-2-one) in high yields.
