  A method for producing an α-acyloxycarbonyl compound of the present invention includes performing an intermolecular reaction between a carboxylic acid and a carbonyl compound selected from the group consisting of ketones, aldehydes, and esters, which have a hydrogen atom at the α-position, using a hydroperoxide as an oxidizer and an iodide salt as a catalyst precursor, thereby introducing an acyloxy group derived from the carboxylic acid into the α-position of the carbonyl compound.

  本发明提供了一种制备α-酰氧基碳酰化合物的方法，包括使用过氧化氢作为氧化剂和碘化物盐作为催化剂前体，通过在羧酸和酮、醛或酯的α位含有氢原子的羰基化合物之间进行分子间反应，从而将来自羧酸的酰氧基团引入到羰基化合物的α位。

  Reaction of cuprates derived from R3MgBr/CuI/LiBr (R3 = n-alkyl) with R1CCCH(O2CR2)2 (R1 = sp2 hybridised substituent, R2 = mainly Me, alkyl, Ph) provides access to allenyl esters R1R3CCCH(O2CR2) (51–88%). Such species are not accessible via rearrangement of precursor propargylic R1R3C(O2CR2)CCH.

  Nonmetallic, chiral organic catalysts are used to catalyze the 1,4-hydride reduction of an α,β-unsaturated carbonyl compound. The α,β-unsaturated carbonyl compound may be an aldehyde or cyclic ketone, and the hydride donor may be a dihydropyridine. The reaction is enantioselective, and proceeds with a variety of hydride donors, catalysts, and substrates. The invention also provides compositions effective in carrying out the 1,4-hydride addition of α,β-unsaturated carbonyl compounds.

• A Bio-Inspired, Catalytic<i>E</i>→<i>Z</i>Isomerization of Activated Olefins
  作者：Jan B. Metternich、Ryan Gilmour

  DOI：10.1021/jacs.5b07136

  日期：2015.9.9

  Herein, Nature's flavin-mediated activation of complex (poly)enes has been translated to a small molecule paradigm culminating in a highly (Z)-selective, catalytic isomerization of activated olefins using (-)-ribo-flavin (up to 99:1 Z/E). In contrast to the prominent Z -> E isomerization of the natural system, it was possible to invert the directionality of the isomerization (E -> Z) by simultaneously truncating the retinal scaffold, and introducing a third olefin substituent to augment A1,3-strain upon isomerization. Consequently, conjugation is reduced in the product chromophore leading to a substrate/product combination with discrete photophysical signatures. The operationally simple isomerization protocol has been applied to a variety of enone-derived substrates and showcased in the preparation of the medically relevant 4-substituted coumarin scaffold. A correlation of sensitizer triplet energy (ET) and reaction efficiency, together with the study of additive effects and mechanistic probes, is consistent with a triplet energy transfer mechanism.
