4-Methylene-3-phenyloxazolidin-2-one (Ia) reacts with peroxybenzoic (or p-nitroperoxybenzoic) acid to give 4-benzoyloxy- (or 4-p-nitrobenzoyloxy-) 4-hydroxymethyl-3-phenyloxazolidin-2-one (IIIa and IIIb). The said esters were submitted to a variety of transformations, in order to secure proof of their structure. 5,5-Dimethyl- and 5,5-pentamethylene-4-methylene-3-phenyloxazolidin-2-one (Ib and c, respectively)
4-亚甲基-3-苯基
恶唑烷-2-酮(Ia)与过氧
苯甲酸(或对硝基过氧
苯甲酸)反应生成4-苯甲酰氧基-(或4-对
硝基苯甲酰氧基-)4-羟甲基-3-苯基
恶唑烷-2-酮(IIIa和IIIb)。为了确保其结构的证明,将所述酯进行了多种转化。5,5-二甲基和5,5-五亚甲基-4-亚甲基-3-苯基
恶唑烷基-2-酮(分别为Ib和c),在用相同试剂处理后会经历双键的氧化裂变,并转化为相应的4-氧代衍
生物XVIb和c。
