S, Yagai.; S, Okamura.; Y, Nakano.; M, Yamauchi.; K, Kishikawa.; T, Karatsu.; A, Kitamura.; A, Ueno.; D, Kuzuhara.; H, Yamada.; T, Seki.; H, Ito. Nature comm., 2014, 5, 4013. DOI: 10.1038/ncomms5013 ...
Performing Asymmetric Catalysis with Thiyl Organocatalysts
An efficient catalyst that is cheap, air and moisture tolerant, with no toxicity…. The development of such a catalyst would merit, at the very least, candidacy for the Nobel prize in Chemistry. Over ...
Claisen Rearrangement
General Characteristics The Claisen rearrangement is the [3,3]-sigmatropic rearrangement of allyl vinyl ethers producing γ,δ-unsaturated carbonyl compounds. This reactions is analogous to the Cope ...
Yamaguchi Macrolactonization
General Characteristics In the method developed by Yamaguchi, hydroxycarboxylic acids (“seco-acids”) are converted into reactive acid anhydrides using 2,4,6-trichlorobenzoyl chloride ...
Organocuprates
General Characteristics The organocuprate reagents [R2CuLi] prepared from copper(I) sources and two equivalents of organolithiums work as strong nucleophiles in 1,4-additions to α,β-unsaturated ...
