An intramolecular organocatalytic cyclopropanation reaction.
Catalytic processes that form functionalized cyclic molecules represent a key transformation for synthetic organic chemistry. Recently, a number of organocatalytic processes have emerged that often provide excellent levels of both enantioand diastereocontrol for the synthesis of cyclic molecules. Our recent studies have identified the utility of ammonium ylides for carbon–carbon bond formation....
متن کاملAsymmetric synthesis of medium-sized rings by intramolecular Au(I)-catalyzed cyclopropanation.
An efficient method for the asymmetric gold(I)-catalyzed preparation of medium sized rings has been developed. The method provides 7- to 9-membered rings in excellent yield. High enantioselectivities can be achieved for 7- and 8-membered ring products employing chiral gold(I) complexes. The results provide insight into the mechanism, showing the fluxional nature of gold(I)-stabilized vinyl carb...

The synthesis of some 13-lactams is described. 'The electronic activation of monocyclic B-lactams provided by a quinonemethine function was found to instabilize the 13-lactam ring toward nucleophilic: attack by water
متن کاملAsymmetric inter- and intramolecular cyclopropanation of alkenes catalyzed by chiral ruthenium porphyrins. Synthesis and crystal structure of a chiral metalloporphyrin carbene complex.
Extensive investigations of asymmetric intermolecular cyclopropanation of terminal alkenes with diazoacetates catalyzed by ruthenium porphyrin [Ru(P*)(CO)(EtOH)] (1, H2P = 5,10,15,20-tetrakis[(1S,4R,5R,8S)-1,2,3,4,5,6,7,8-octahydro-1,4:5,8-dimethanoanthracene-9-yl]porphyrin) and the application of catalyst 1 to asymmetric intramolecular cyclopropanation of allylic or homoallylic diazoacetates a...
متن کاملAu(I)-catalyzed intramolecular oxidative cyclopropanation of 1,6-enynes derived from propiolamides with diphenyl sulfoxide.
We have developed gold(I)-catalyzed oxidative cyclopropanation of 1,6-enynes derived from propiolamides employing diphenyl sulfoxide as an oxidant. 1,6-Enynes having a terminal alkyne and a propiolamide tether efficiently transformed into cyclopropane carboxaldehyde derivatives.
