چکیده

The development of an enantioselective catalytic Claisen rearrangement1 remains an important yet elusive goal in chemical synthesis.2 With this objective in mind, we recently reported the acyl-Claisen rearrangement, a Lewis acid-catalyzed variant of the Bellus reaction3 that utilizes acid chlorides and allylic amines in the stereoselective synthesis of R,â-disubstituted-γ,δ-unsaturated carbonyls (eq 1).4 In this communication, we demonstrate that

Non-carbonyl-stabilized metallocarbenoids in synthesis: the development of a tandem rhodium-catalyzed bamford-stevens/thermal aliphatic claisen rearrangement sequence.

A tandem rhodium-catalyzed Bamford-Stevens/Claisen rearrangement is presented. The tandem reaction uses Eschenmoser hydrazones for the in situ generation of non-carbonyl-stabilized diazo alkanes, which are presumably intercepted by Rh(II) catalysts to induce a 1,2-hydride migration. This sequence provides high levels of stereocontrol for the generation of simple acyclic (Z)-enol ethers. These e...

Stereo- and regioselective organic transformations based on main group organometallic reagents- application to the stereocontrolled Claisen rearrangements

Unprecedented stereocontrolled Claisen rearrangement of allylic vinyl ethers has been developed with modified organoaluminum reagents A and B as an example of diastereoselective activation of ethereal substrates. The stereoselective activation of ether moiety is the subject of our current interest. Oxygenophilic organoaluminum reagents are known to exhibit the great tendency to form stable ethe...

Gold(I)-Catalyzed Desymmetrization of 1,4-Dienes by an Enantioselective Tandem Alkoxylation/Claisen Rearrangement.

An enantioselective alkoxylation/Claisen rearrangement reaction was achieved by a strategic desymmetrization of 1,4-dienes under the catalysis of (S)-DTBM-Segphos(AuCl)2/AgBF4. This reaction system was highly selective for the formation of 3,3-rearrangement products, providing cycloheptenes with various substitutions in good yield and good to excellent enantioselectivity. This transformation wa...
