Article Title: | Remarkable stereoselectivity in the alkylation of a hydroazulenone: Progress towards the total synthesis of guanacastepene |
Abstract: | exo-Methylene ketone 6 serves as a vehicle for elaboration of the C8 quaternary center en route to guanacastepene via a conjugate addition-alkylation sequence. Methylation of the cycloheptadienolate derived from 7 is highly selective for the desired relative stereochemistry, as determined by NMR and crystallographic analysis. © 2001 Published by Elsevier Science Ltd. |
