Nucleophilic Addition to Azoalkenes; Diastereoselective Synthesis of β-Hydroxy Ketones and β,γ-Fused γ-Lactams
The α-alkylation of ketones and their derivatives by the addition of their corresponding enolates to alkyl halides is a fundamental synthetic transformation, but its utility is limited because the key bond-forming step proceeds in a bimolecular nucleophilic substitution fashion. Here in the first …

1. C-C Bond Formation via Soft Enolization and Umpolung-like Chemistry 2. Electrophilic Fluorination of Organozinc Reagents
… Our approach towards uses a novel β-silylated azoalkenes intermediate towards anti-diastereoselective α-alkylation of ketones. In addition, we explored a streamlined approach towards monofluorohydrocarbon formation via electrophilic fluorination of organozinc compounds. We hope this will have …
