A manufacturing route for the synthesis of raltegravir potassium 1 was developed via a thermal rearrangement of amidoxime DMAD adducts 6 to construct the key, highly functionalized hydroxypyrimidinone core 7. Utilizing this route 1 was prepared in nine linear chemical steps with 22% overall yield. A second-generation synthesis was subsequently developed that solved the key chemical, productivity, and environmental impact issues of the initial synthesis. Highlights of the new synthesis include a highly selective methylation, 3-4-fold higher productivity, and a 65% reduction of combined organic and aqueous waste produced. The efficient second-generation manufacturing route provides raltegravir potassium 1 in 35% overall yield.

(Chemical Equation Presented) Break up to make up: Combined experimental and computational studies provide evidence that the key step in the synthesis of a novel anti-HIV drug involves an unprecedented stepwise radical pair rearrangement mechanism in which radical fragments are held together by strong electrostatic forces (see scheme); this is favored over alternative mechanisms involving concerted pericyclic rearrangement.
