Abstract:
Without employing any transition metal, a mild, practical, and environmentally attractive methodology has been developed for the chloroazidation of 1,6-enynes at room temperature. In this radical cascade process, three new chemical bonds, including C–Cl (Br, I), C–N, and C–C bonds, are formed in one step for the construction of 2-pyrrolidinones. The method is valuable because of its mild reaction conditions, operational simplicity, and the rich biological activity of the corresponding 2-pyrrolidinone products.

Abstract:
Pd/DPEphos catalyzes the [3+2] cycloaddition of various alkyl isocyanates with 2-acetoxymethyl-3-allyltrimethylsilane as a synthetic equivalent of trimethylenemethane (TMM). Taking advantage of 2-acetoxymethyl-3-allyltrimethylsilane acting both as nucleophile as well as electrophile this reaction gives a convenient access to 5-ring lactams with an exocyclic alkene moiety. The formation of the β,γ-unsaturated 2-pyrrolidinones occurs without olefin isomerization and without epimerization of the stereogenic centers. Mechanistic investigations suggest an initial N-allylation of the isocyanate foll

Abstract:
A coupling reaction between cyclic N-acyliminium ions with organozinc reagents is described. The cyclic N-acyliminium ions, generated in situ from N-substituted-5-hydroxy-2-pyrrolidinones by treatment with boron trifluoride–diethyl ether complex or titanium tetrachloride, are trapped by the organozinc reagent, which is formed from an alkyl bromide in the presence of zinc in the same reaction medium. The N-substituted-5-allyl-2-pyrrolidinones generated using this method serve as versatile intermediates for the synthesis of azabicyclic systems with indolizidine and pyrroloazepinolizidine cores.
