Analysis of the sequences of the regions of the viral genome encoding the entire VP1, the VP1/2A junction and parts of VP3 allowed us to detect and characterize the first naturally occurring recombinant of HAV. Moreover, comparison of the sequences of the entire VP1 of these isolates led ...
The addition of enynic phosphonatesto alcohols in the presence of boron trifluoride, leads to γ,δ-ethylenic β-ketophosphonates.Yields of 70% have been obtained. WhetherZorEenynic derivates are starting materials theEketophosphonate is obtained in both cases. The dipole moments of both ...
