Novel macrocyclic bis[ruthenium(II)bipyridyl] and ruthenium(II) bipyridyl-metallocene receptors are prepared and shown by 1H NMR and fluorescence emission spectroscopy to exhibit remarkable selectivity for the chloride anion in preference to dihydrog

New upper-rim bis[rhenium(I) bipyridyl, ruthenium(II) bis(bipyridyl), cobaltocenium]calix[4]arene receptors exhibit remarkable dihydrogen phosphate selective anion recognition properties dictated by the relative positions of lower-rim tosyl substitue

Enantiospecific syntheses of furo[f]indolizines with different degrees of unstauration (4a,b, 8a, 9a, and 10a) as analogues of phenanthro[f]indolizidine alkaloids have been completed from (S)-glutamic acid in a few-step sequence. This was achieved fr

The furo[2,3(or 3,2)-f]indolizidinediones 4a,b were synthesized in five steps from glutamic acid in good yield. The ketones were converted into trans alcohols 5a,b or oximes 6a,b (either as syn-anti mixture or as single isomer). The selectivity of th
