Novel synthetic routes, which are highly applicable for industrial preparation of therapeutically beneficial oxidized phospholipids are disclosed, and the oxidized phospholipids obtainable via these routes. Particularly, novel methods for efficiently preparing compounds having a glycerolic backbone and one or more oxidized moieties attached to the glycerolic backbone, which are devoid of column chromatography are disclosed. Further disclosed are novel methods of introducing phosphorous-containing moieties such as phosphate moieties to compounds having glycerolic backbone and intermediates formed thereby.

cycloadditions involving benzyne intermediates. The precursor offers an efficient alternative for generating benzynes compared to widely used ortho TMS triflates under similar reaction conditions. With the utilization of this new precursor, the formation of potentially genotoxic trifluoromethanesulfonate side product is eliminated. The applicability of the new benzyneprecursor was demonstrated in different
