Scheme 7. Oxidative degradation of 38-hydroxymycalolide B (37). The 8R and 9S ACs of 37 were assigned by perruthenate degradation and conversion to bis-p-bromophenacyl derivative 49 (Scheme 7) and comparison to authentic standards by chiral HPLC (Chiralcel OD). Finally, the configur...
3-Bromocarbazole synthesis: A solution of N-bromosuccinimide (1.1g, 5.98mmol) in dimethylformamide was added dropwise to a solution of carbazole (1, 1g, 5.96mmol) in dimethylformamide (15mL) at 0°C. The reaction mixture was then stirred at room temperature for 24h. The reaction was poured ...
The procedure for the synthesis of compounds 2a–r is similar to the one previously employed for the sulfonylation of the analogous 2,4-dihydroxyacetophenone and 2‑hydroxy-4-methoxyacetophenone [17]. A stirred mixture of an indazole derivative 1 (1 equiv.) and potassium carbonate (1.1 equiv...
The reaction proceeded up to the theoretical degree of conversion without loss of crystallinity, and it was also performed on a preparative scale with good yield. Moreover, it represents the first synthetic pathway to (E)-1,2-dibromo-1,2-diethynylethenes, which could serve as synthetic ...

A facile Pd-catalyzed conversion of aryl and vinyl triflates to aryl and vinyl halides (bromides and chlorides) is described. This method allows convenient access to a variety of aryl, heteroaryl, and vinyl halides in good to excellent yields and with greatly simplified conditions relative to ou...
(ACADVL) mediates the oxidation of the acyl-CoA while FAD is reduced to FADH2; enoyl-CoA hydratase (ECH1) facilitates hydration; 3-hydroxy acyl-CoA dehydrogenase (HADHA) mediates an additional redox step where NADH is released, and 3-ketoacyl CoA thiolase (HADHB) mediates thiolysis, ...
