An improved synthesis of the indole unit, a key intermediate for eudistomin C, was established utilizing Makosza's indole synthesis. A concise total synthesis of eudistomin E was achieved on the basis of the improved synthesis.
reported in the literature have been prepared and characterized. 2-Thymoloxyacetamidine, 2-(2,6-xylyloxy)acetamidine, 2-(2,6-dichlorophenoxy)acetamidine, 2-(2,6-dimethoxyphenoxy)acetamidine, 2-benzyloxyacetamidine, and their N-methyl and N,N-dimethyl derivatives were evaluated for their potential cardiovascular effects. None of these compounds showed any potent pharmacological activities in a general

Calix[4]arenes 3a (R = OMe) and 3b (R = NO2) with 5,17-bis[4-(4-substituted-phenyl)azo] and 25,27-bisoxymethyltetrazole groups were synthesized by 1,3-dipolar cycloaddition of oxyacetonitrile azocalix[4]arenes 2a and 2b activated with trimethylsilyl azide. UV/Vis screening of 3a and 3b with 14 metal ions showed that 3a (with p-methoxyphenylazo substituent) was a highlychromogenicsensor to Ca2+, whereas
