Chloroallyl anion : Highly regio- and diastereoselective α-addition of chloroallyl zinc reagent to carbonyl compounds

Palladium Pincer Complex Catalyzed Cross‐Coupling of Vinyl Epoxides and Aziridines with Organoboronic Acids

“…[18] The vinyl epoxides and aziridines were prepared according to literature procedures. [36,37] The boronic acids are commercially available and were used as received.…”

Preparation and ring-opening reactions of N-diphenylphosphinyl vinyl aziridines

“…We anticipated that the reaction of α-lithio allyl bromide [31–38] with an N -Dpp imine would furnish vinyl aziridines by an aza-Darzens-like reaction. This hypothesis was validated by a reaction of this anion with N -Dpp benzaldimine at −78 °C in the presence of solid ZnCl 2 , which delivered predominantly ( E ) - aziridine 1 ( 3 J = 2.6 Hz; d.r.…”

Highly Stereoselective Prins Cyclization of (Z)‐ and (E)‐γ‐Brominated Homoallylic Alcohols to 2,4,5,6‐Tetrasubstituted Tetrahydropyrans.

“…Proton nuclear magnetic resonance spectra ( 1 H NMR) were recorded on a Bruker Avance DPX 300 and Bruker AMX 400 & 500 spectrophotometers (CDCl3 as solvent). Chemical shifts for 1 H NMR spectra are reported as δ in units of parts per million (ppm) downfield from SiMe 4 (δ 0.0) and relative to the signal of chloroform-d (δ 7.2700, singlet). Multiplicities were given as: s (singlet); d (doublet); t (triplet); q (quartet); qu(quintet); dd (doublets of doublet); ddd (doublets of doublets of doublet); dt (doublets of triplet); td (triplets of doublet) or m (multiplets).…”
