چکیده

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 carbenoid intermediates.

Development of transition-metal-catalyzed cycloaddition reactions leading to polycarbocyclic systems*

We present a compilation of methodologies developed in our laboratories to assemble polycyclic structures containing smalland medium-sized cycles, relying on the use of transition-metal-catalyzed (TMC) cycloadditions. First, we discuss the use of alkylidene cyclopropanes (ACPs) as 3C-atom partners, in particular in their Pd-catalyzed (3 + 2) cycloadditions with alkynes, alkenes, and allenes, re...

Synthesis of functionalized cyclohexenone core of welwitindolinones via rhodium-catalyzed [5 + 1] cycloaddition.

The cyclohexenone core of welwitindolinones was synthesized by a Rh(I)-catalyzed [5 + 1]-cycloaddition of an allenylcyclopropane with CO. A pentasubstituted cyclopropane was prepared successfully by a Rh(II)-catalyzed intramolecular cyclopropanation of alkenes with chlorodiazoacetates.

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....
