1,3-dithiane

1,3-Dithiane (1,3-Dithian) is a protected formaldehyde anion equivalent that could serve as a useful labeled synthon. 1,3-Dithiane is also a sulfur-containing Maillard reaction products found in boiled beef extracts.

Neopatulin is an isomer involved in redox reactions and serves as a crucial biosynthetic precursor to the potent antibiotic patulin, which is produced by various fungi. It can be synthesized through a Lewis acid-catalyzed aldol condensation reaction or via the reaction of 2-formyl-1,3-dithiane with 2-(tert-butyldimethylsiloxy)-4-[(tert-butyldimethylsiloxy)methyl]furan.
