A 'dithiolane' is a
sulfur heterocycle derived from
cyclopentane by replacing two
CH2 groups with
thioether groups. The parent compounds are '1,2-dithiolane' and '1,3-dithiolane'.
1,2-dithiolanes, such as
lipoic acid, are cyclic
disulfides
1,3-dithiolanes are important as
protecting groups for
carbonyl compounds, since they are inert to a wide range of conditions. Reacting a carbonyl group with
1,2-ethanedithiol converts it to a 1,3-dithiolane, as detailed below.
