A non-natural hydroxy-elemane was found amenable to divergent transformations, producing either polyunsaturated guaianes under basic, oxygen-free conditions, or oxidized furogermacranes when anionic oxy-Cope reaction quenched by an oxidant is employed. Based on these findings, the first total syntheses of zedoarol and gweicurculactone are reported.
发现一种非天然的羟基-elemane可以进行发散的转化,在碱性,无氧条件下产生多不饱和的愈创树,或在使用氧化剂将阴离子氧基-Cope反应淬灭后,生成氧化的呋喃基呋喃。基于这些发现,报道了齐多洛尔和异丁烯二内酯的第一批总合成。
