WebFeb 4, 2024 · PCC was invented as a workaround to this problem: it works as a reactant in anhydrous enviroment, hence stopping the reaction at the aldheyde stage. An alternative way to see PCC is to follow its preparation: if you add C r O X 3, H C l and pyridine, PCC is formed. If you add C r O X 3, acid and water, chromic acid is formed. WebJan 15, 2024 · The total synthesis of (−)-antrocin and its enantiomer are presented. Antrocin (−)-1 is an important natural product which acts as an antiproliferative agent in a metastatic breast cancer cell line (IC50: 0.6 μM). The key features of this synthesis are: (a) selective anti-addition of trimethylsilyl cyanide (TMSCN) to α,β-unsaturated ketone; (b) …

WebPyridinium chlorochromate ( PCC) is a milder version of chromic acid. PCC oxidizes alcohols one rung up the oxidation ladder, from primary alcohols to aldehydes and from secondary alcohols to ketones. Unlike chromic acid, PCC will not oxidize aldehydes to carboxylic acids. WebThe Jones reaction uses aqueous, acidified dichromate. In aqueous solution, the aldehyde forms a 1,1-diol, which is easily oxidized to a carboxylic acid. RCH₂OH → RCHO ⇌ RCH …
