Background The feasibility and safety of endoscopic thyroidectomy were evaluated by an approach of systematic review of published studies in the past decade.Met
A convenient, rapid and efficient method for the synthesis of substituted steroidal [6,7-d] thiazoles using microwave-induced organic reaction enhancement chemi
The monomer 2,6,12-triaminotriptyeene was synthesized and the structure was confirmed by IR and 1H NMR spectra. Hyperbranched polyimides modified with different
1,3,5-Trisubstituted pyrazolines were oxidized to the corresponding pyrazoles in high yield with tris(4-bromophenyl)aminium (TBPA+·) hexachloroantimonate in ch
