So far, in addition to halogen atoms, other non-metallic atoms can become part of the aromatic heterocycle, and the target ring system is still aromatic.Chittari, Pabba; Hamada, Yasumasa; Shioiri, Takayuki researched the compound: Ethyl oxazole-5-carboxylate( cas:118994-89-1 ).Safety of Ethyl oxazole-5-carboxylate.They published the article 《Synthetic studies on bengazoles of marine sponge origin. Synthesis of the core bis-oxazole fragments》 about this compound( cas:118994-89-1 ) in Synlett. Keywords: bisoxazole bengazole core preparation; oxazole bengazole core preparation. We’ll tell you more about this compound (cas:118994-89-1).
The core bis-oxazole fragment I (R = OCH2OMe, R1 = CHO) was constructed by the coupling of 5-formyloxazole with lithiated 5-(silyoxymethyl)oxazoles, oxidation of the resulting bis(oxazolyl)methanol (II), followed by the asym. reduction with (R)-(+)-BINAL-H as key steps. Addnl., preparation of bis-oxazole fragment I (R = H, R1 = CH2OSiPh2CMe3) was accomplished by the Barton-McCombie radical deoxygenation reaction of II.
After consulting a lot of data, we found that this compound(118994-89-1)Safety of Ethyl oxazole-5-carboxylate can be used in many types of reactions. And in most cases, this compound has more advantages.
