Allylic fluorination via an unusual alkene Z/E isomerisation
摘要:
The isomerisation of readily available (Z)-4-(para-methoxybenzyloxy)- 1 -chloro-2-butene was achieved under mild conditions to afford the much less accessible E-diastereoisomer. This was an effective Substrate in Sharpless asymmetric dihydroxylation (AD) reactions, delivering highly enantiomerically enriched fluorinated butene triol building blocks.
