资源简介：
Gold(I) complexes
bearing sterically demanding phosphine ligands
such as tBuXphos catalyze the cascade
Rautenstrauch rearrangement/[4 + 3] cycloaddition of 1-ethynyl-2-propenyl
esters. The reaction provides an efficient and straightforward route
to bicyclo[3.2.1]octa-3,6-dienes with high regio- and stereoselectivity.
The formation of the [4 + 3] cycloadducts likely proceeds through
the cycloaddition of a gold(I) carbenoid/gold-stabilized allyl cation
intermediate with cyclopentadiene arising from Rautenstrauch rearrangement.
