The reaction of 2, 4, 6-trimethoxyphenyl-lead triacetate (4) with 3,5-di-t-butylphenol (1) at room temperature afforded the very hindered phenol (5) in good (87%) yield; acetylation gave the acetate (7) which was fully characterised, including an X-r

Sinefungin 1a and 6-epi-sinefungin 1b have been prepared from adenosine and L-aspartic acid. The key step in the synthesis was the coupling of the radical derived from 14 with the unsaturated amide 13. The latter was obtained by a radical reaction fr

Photolysis of N-hydroxy-2-thiopyridone esters derived from uronic acids or α-amino acids in presence of vinyl phosphonate affords the corresponding phosphonate derivatives. A convenient route for the synthesis of the isostere of AZT-5′ monophospha

The synthesis and radical reduction of thiocarbonyl derivatives of methyl 3,6-anhydro pyranosides has been studied in the α-D-gluco, α-D-manno and β-D-galacto series. A cyclic intermediate is proposed to explain the fact that bis-deoxygenation onl

The action of sodium hydrogen telluride, NaTeH, on non electrophilic carbon-arbon double bonds has been investigated.The reaction is found to be very sensitive to the substituents on the ethylenic linkage. Whereas phenyl conjugated olefins are reduce
