<i>Tert</i>-Butyl Nitrite Mediated Expeditious Methylsulfoxidation of Tetrazole-amines with DMSO: Metal-free Synthesis of Antifungal Active Methylsulfinyl-1<i>H</i>-tetrazole Derivatives
A tert‐butyl nitrite mediated methyl‐sulfoxidation of tetrazole‐amines in neat DMSO or methyl‐sulfinyl derivatives is revealed for the first time. The reaction exhibits good group tolerance, as well as highly selectivity to sulfinyl substitutions. This new protocol provides an expeditious and operationally simple procedure for C−S(O) bond construction. Preliminary bioactivity evaluation on selected

and orthogonally. As the follow-up studies of the diazo transfer reaction using FSO2N3, we discover that amidines and guanidines are rapidly transformed into tetrazole derivatives when reacting with FSO2N3 under an aqueous environment, which is unprecedented for tetrazole synthesis.
在此,我们报道了在温和条件下通过 FSO 2 N 3实现四唑的简便合成。FSO 2 N 3已被证明是最强大的重氮化试剂,可将数千种伯胺快速且正交地转化为叠氮化物。作为FSO 2 N 3重氮转移反应的后续研究,我们发现脒和胍在水相环境下与FSO 2 N 3反应时迅速转化为四唑衍生物,这对于四唑合成来说是前所未有的。
