Synthesis of benzonorcaradienes by gold(I)-catalyzed [4+3] annulation.

چکیده
A formal [4 + 3]-annulation of vinyl arenes and diynyl propargyl esters is described. A mechanism involving cationic phosphinegold(I)-catalyzed tandem cyclopropanation/hydroarylation to produce the benzonorcaradiene products is proposed. In accord with this mechanism, the alkynyl cyclopropane can also be prepared with excellent regio- and diastereocontrol.

Synthesis of azepines by a gold-catalyzed intermolecular [4 + 3]-annulation.
A convenient gold(III)-catalyzed synthesis of azepines from the intermolecular annulation of propargyl esters and alpha,beta-unsaturated imines is reported (19 examples, 55-95% yield). This formal [4 + 3]-cycloaddition reaction is proposed to proceed via a stepwise process involving intramolecular trapping of an allyl-gold intermediate.
متن کاملGold-catalyzed efficient synthesis of azepan-4-ones via a two-step [5 + 2] annulation.
A surprisingly efficient synthesis of azepan-4-ones via a two-step [5 + 2] annulation is developed. This reaction involves a key gold catalysis and shows generally high regioselectivities and good to excellent diastereoselectivities.
متن کاملGold(I)/Zn(II) catalyzed tandem hydroamination/annulation reaction of 4-yne-nitriles.
The tandem hydroamination-annulation reaction of 4-pentyne-nitriles in the presence of amine nucleophiles and a cooperatively operating catalyst system, consisting of Ph(3)PAuCl and Zn(ClO(4))(2), provides an efficient route to 2-aminopyrroles. Two regioisomeric 2-aminopyrroles were formed in moderate to good yields.
متن کاملGold-catalyzed efficient synthesis of 2,4-disubstituted furans from aryloxy-enynes.
A series of (E)-1-aryloxy-1-en-3-ynes has been prepared by Sonogashira coupling of 2-bromo-3-aryloxypropenoates with terminal alkynes using Pd(PPh(3))(4) and CuI as the catalysts in Et(3)N. The resulting enynyl-aryl ethers are found to be highly applicable to the synthesis of 2,4-disubstituted furans with an ester group at C-4 position through an Au/Ag-catalyzed annulation reaction under extrem...
متن کاملN-heterocyclic carbene-catalyzed [4 + 1] annulation of phthalaldehyde and imines.
The diastereoselective synthesis of cis-2-amino-3-hydroxyindanones was realized by the N-heterocyclic carbene-catalyzed [4 + 1] annulation of phthalaldehyde and imines, which may involve a tandem aza-benzoin reaction and aldol reaction.
