Abstract
9 yield. Then in an application of our new alkene synthesis, 6 the 0-keto ester was converted into the corresponding enol phosphate'(NaH, CIPO (OEt) 2, Et20, O" C), which was coupled with lithium dimethylcuprate (Et20,-78--23" C) to yield the a, P-unsaturated ester 6 in 85-92% yield from 5. The ester 6 was reduced (LiAIH4, Et20, reflux, 92-98%), and the resulting alcohol was converted into the allylic bromide 7 using the two-phase procedure of van ...
