Disclosed are methods of making delmopinol and delmopinol salts (e.g., delmopinol metal salts, such as, for example, delmopinol calcium salts, delmopinol sodium salts, delmopinol potassium salts, and/or delmopinol magnesium salts). Delmopinol has structure (I) and a salt of delmopinol has structure (II).

A general, efficient, and site-selective visible light-induced Pd-catalyzed remote desaturation of aliphatic alcohols into valuable allylic, homoallylic, and bis-homoallylic alcohols has been developed. This transformation operates via a hybrid Pd-radical mechanism, which synergistically combines the favorable features of radical approaches, such as a facile remote C-H HAT step, with that of transition-metal-catalyzed chemistry (selective β-hydrogen elimination step). This allows achieving superior degrees of regioselectivity and yields in the desaturation of alcohols compared to those obtained by the state-of-the-art desaturation methods. The HAT at unactivated C(sp3)-H sites is enabled by the easily installable/removable Si-auxiliaries. Formation of the key hybrid alkyl Pd-radical intermediates is efficiently induced by visible light from alkyl iodides and Pd(0) complexes. Notably, this method requires no exogenous photosensitizers or external oxidants.
Direct transformation of allylic and benzylic thiols, thioethers, and disulfides into organolithium compounds

The reaction of allylic and benzylic thiols 1, disulfides 3, and thioethers 4 and 5 with an excess of lithium and a catalytic amount of 4,4′-di-tert-butylbiphenyl (DTBB, 5mol%) afforded the corresponding allylic and benzylic organolithium reagents via reductive cleavage of the carbon-sulfur bond. The generated organolithium compounds gave the expected products 2 by reaction with several electrophiles followed by hydrolysis with water. The reaction conditions and the lithiation procedure (stepwise of Barbier-type process) depended on the starting sulfur containing compound.
