NMR spectra (in [D],DMF) of natural D and synthetic 4 were essentially identical, particularly in the region representing olefinic protons (6 = 5.6-6.8). This, in turn, proves that the the component D is pure all-trans-fecapentaene-14 (4). We have also established that the CI mass spectra of the na

The lithiation of a soluble chloromethylated polystyrene 1 (prepared by AIBN-induced copolymerisation of styrene and 4-chloromethylstyrene in 3:1 molar ratio) with an excess of lithium powder and a catalytic amount (10%) of DTBB, and reaction with different electrophiles leads, after hydrolysis, to
