Efficient coupling of allylstannane with Diels-Alder cycloadducts derived from 4-bromo-substituted masked o-benzoquinones: Synthesis of 5-allyl-oxatricyclo[m.3.1.0]decenones and undecenones

摘要

In the presence of a catalytic amount of Pd(PPh3)(4), allylstannane coupled efficiently with oxatricyclic [m.3.1.0] bromo-decenones and bromo-undecenones to afford the corresponding 1,4-dienes in excellent yields.
