具有≥96% 对映体过量的 α,β-丁烯内酯是由 β,γ-丁烯内酯通过新型 Cu(I)-配体协同催化合成的。该反应由具有远程叔氨基的手性联苯-2-基膦配体实现。密度泛函理论研究支持金属中心和配体碱性氨基在初始软去质子化和关键不对称γ-质子化过程中的合作。值得注意的是,其他造币金属,即 Ag 和 Au,在这种不对称异构化化学中可以很容易地承担与 Cu 相同的作用。

general olefin isomerization was realized via biomimetic protontransfer catalysis with a new chiral organic catalyst. A broad range of mono- and disubstituted β,γ-unsaturated butenolides were transformed into the corresponding chiral α,β-unsaturated butenolides in high enantioselectivity and yield in the presence of as low as 0.5 mol % catalyst. Mechanistic studies have revealed the protonation as the
The present invention relates to, inter alia, extracellular drug conjugates (EDC) in which an antibody or other targeting agent (e.g. a targeting moiety) is linked to a drug through a linker (e.g. a non-cleavable linker). These conjugates are useful in the treatment of disease and/or as a tool in the evaluation of biological systems.
