DOI: 10.1039/d3qo00412k
Abstract: Herein, we design and develop a one-pot cascade strategy for the assembly of multi-substituted conjugate oxindole derivatives. This approach represents a new reaction mode for carbene gem-difunctionalization by delayed acyl transfer instead of delayed proton… read more here.

DOI: 10.1055/s-0037-1611743
Abstract: In order to circumvent reactivity or selectivity issues associated with the addition of enolates to electrophiles, chemists have devised innovative methods involving transient activating groups. One of these powerful methods consists of the use of… read more here.
