In our approach towards Paulitin, a sesquiterpene lactone, we have shown that steric hindrance at the propargylic position is of importance to the outcome of enyne metathesis. Moreover, we have uncovered further evidence to confirm that the alkyne-first pathway should be the favored process in enyne metathesis.
在我们对 Paulitin(一种
倍半萜内酯)的研究中,我们发现炔丙位置的空间位阻对于烯炔复分解的结果非常重要。此外,我们还发现了进一步的证据来证实
炔烃优先途径应该是烯炔复分解中优选的过程。
