Synthesis of diverse pyrazole-4-sulfonyl chlorides starting from 2-(benzylthio)malonaldehyde
Mol. Diver. 2016, 20 (1), 1-7
A series of pyrazole-4-sulfonyl chlorides was obtained by a convenient 2-step method starting from synthetically available 2-(benzylthio)malonaldehyde. The method can be applied for the effective multi-gram synthesis of diverse pyrazole-containing sulfonyl chlorides which are mostly not available by other methods.
