A carefully designed three-step unsaturation of carboxylic acids is described. Briefly, carboxylic acids were converted to the trifluoromethyl ketone. Subsequent treatment with selenium dioxide followed by hydrolysis afforded α,β-unsaturated carboxylic acids. The mechanism of the reported transformation was investigated, which led us to propose a novel explanation featuring selenium dioxide ...

Prior studies have shown that applications of the synthetic auxin 2,4-dichlorophenoxyacetic acid (2,4-D) to the foliage of potato plants can reduce common scab. Here field and glasshouse trials suggest that 2,4-D foliar treatments may also reduce the biologically distinct tuber disease, powdery scab. Significant correlations between suppression of common and ...

6-Substituted amino-penicillanic acid esters were synthesized starting with 6-apa. The compounds containing a 1,3-thiazole- or 1,3-thiazolidinone nucleus linked to the penicillanic acid skeleton via a hydrazino linkage were obtained from 6-apa. The treatment of carbonylamino and carbonothioylamino compounds with 4-chlorophenacyl bromide or ethyl bromoacetate gave 6-bis{4-[1,3-thiazol(idinone)amino]benzoyl}amino derivatives of 6-apa.
