2024年1月31日 · By combining DFO with an iridium catalyst, direct asymmetric α-C−H alkylation of NH 2 -unprotected primary alkyl amines with allylic carbonates has been achieved. This …

2024年2月10日 · In this review, we aim to gather the most relevant recent work published since 2011 dealing exclusively with the asymmetric allylation of carbonyl compounds using free …

Cyclic ketone enolates were successfully transformed through an asymmetric allylic alkylation using an iridium based catalyst by Hartwig (Scheme 14 a). New quaternary centers were …

2024年1月29日 · This review describes the catalytic asymmetric allylic alkylation (AAA) of acyclic prochiral nucleophiles, namely enolates, as a means of accessing congested quaternary and …

2024年2月10日 · Even more interesting is the catalytic asymmetric allylic alkylation (AAA) of carbonyl compounds (asymmetric Tsuji− Trost allylation), which generates at least a …

2022年12月8日 · Here we report the structural characterization and transformations of the previously assumed putative anti -π-allyliridium intermediates. These complexes are highly …

4 天之前 · Asymmetric multicomponent reactions that aim to control multiple chiral centers with high selectivity in a single step remain an on-gonging challenge. The realm of enantioselective …

Among asymmetric catalytic processes, metal catalyzed asymmetric allylic alkylations (AAA) are unique in two respects – first, they have multiple mechanisms by which asymmetry can be …

3 天之前 · A catalytic asymmetric method for the synthesis of γ-substituted ketones via hydrogen borrowing alkylation of both racemic linear precursors and 1,5-diols is described. The base …
