Three synthetic strategies for the construction of tert-butyl (E)-3-arylprop-2-en-1-ol carbonates are described. Complementary approaches employing Suzuki-Miyaura coupling and cross-metathesis reaction gave moderate yields of the title compounds in o

Highly active magnesium (Rieke magnesium) reacts with fluorohalomethanes at −100 °C forming the corresponding fluorohalomethylmagnesium halides, which undergo nucleophilic substitution with silyl halides or nucleophilic addition with aldehydes or

Enantiomerically pure 1-arylpropenols 8 have been prepared by resolution of the corresponding racemates, using the lipase formulation Novozyme 435. Deprotonation of the latter alcohols with n-BuLi, followed by derivatization with (t-BuO)2CO, afforded

Iridium(I)-catalyzed allylation of the enantiopure monoprotected copper(I) alkoxide, generated from (S)-5a, with the enantiopure allylic carbonates (R)-9a,b has been developed as the key step in a new approach to C-nucleoside analogues. The anomeric
