Abstract

Daniel Ve'gha, Jean Morelb. Bernard Decroixb and Peter ZdlupsGa ... Cyclocondensation of the benzylic-type thiols (Ib-VIb) in ortho position on aromatic and heteroaromatic carboxylic acids to form the corresponding thiolac- tones (Ic-VIc) can be effected with polyphosphate esters (PPE) in organic sol- vents in 75-90% yields. ... Growing interest in the synthetic utilization of aromatic and heteroaromatic thio- ... We reported3, the formation, in 3040% yield, of ...
