The lithium enolate of the â-lactone 10 was reacted with 1,2-dibromoethyl ethyl ether to furnish 12, treatment of which with aqueous K2CO3 gave a highly functionalized sesquiterpene of the monocyclofarnesyl skeleton the 3-substituted furan-2(5H)-one 13a.
将â-内酯10的锂烯醇盐与1,2-二溴乙基乙基醚反应,得到12,再用水合K2CO3处理12,获得高度官能化的倍半萜烯,即单环法尼基骨架的3-取代呋喃-2(5H)-酮13a。
