Hoʻohana ʻia ka 2,3-Dichloro-5,6-Dicyano-1,4-Benzoquinone (DDQ) (CAS: 84-58-2) ma ke ʻano he oxidizing agent, ʻoi loa i ka synthesis steroid.
Loaʻa i ka DDQ nā noi like ʻole.ʻO DDQ kahi mea hoʻopale pale no nā ketals, acetals, a me thioacetals.He mea pono e hoʻololi i ka electron reagent no ka synthesis o nā quinolones a me kahi mea oxidizing i hoʻohana ʻia e synthesize steroids.Hoʻohui ʻia, hoʻohana ʻia ka DDQ me Ph3P e synthesize 1,2-benzisoxazoles.
ʻO ka DDQ kahi mea hoʻoheheʻe oxidation ikaika, i hoʻohana nui ʻia i ka dehydrogenation o nā pūhui, ʻoi aku hoʻi no nā pūhui steroid.Loaʻa iā ia ke koho maikaʻi a he mea hoʻoheheʻe oxidation nui i ka ʻoihana steroid.Me ka hohonu o ka noiʻi ʻana, ʻike ʻia ʻo DDQ e hōʻike ana i kahi manaʻo noi maikaʻi i nā hopena kūlohelohe.No ka laʻana, koho oxidation o alcohols, oxidation ma ka benzyl kulana o ka aromatic apo, kukuluia'na o carbon-carbon paʻa, ho okumu ana o carbon heterobonds, Cyclization Reactions, pale a me ka deprotection, a me na mea like.Hoʻohana ʻia ma ke ʻano he lāʻau lapaʻau, ma ke ʻano he dehydrogenation agents no nā pūhui hormone steroid.
Hoʻohana nui ʻia ʻo DDQ i nā hopena kūlohelohe, a ke hoʻonui nei hoʻi kāna mau noi noi.ʻO ka hoʻomohala ʻana i nā kahua noi hou, ʻoi aku ka nui o ka oxidative coupling cyclization reaction, ʻo ia ke ʻano hoʻomohala nui o DDQ i ka noiʻi noiʻi o nā hopena kūlohelohe.
Hoʻopili ʻo DDQ (CAS: 84-58-2) me ka wai e hoʻokuʻu i ka hydrogen cyanide ʻona loa (HCN).Hoʻonui ka haʻahaʻa haʻahaʻa a me ka ʻakika palupalu i ka paʻa o DDQ.Pono e mālama i kahi maloʻo.
