Indirect electroreductive sequential radical reaction catalyzed by a Ni(II) complex. One-step preparation of functionalized (methylene)cyclopentanes

Substituted (methylene)cyclopentanes were prepared by one-step reaction at room temperature from butynyl iodides and activated olefins by sequencing of free radical addition and cyclization reactions. The reactions, which were conducted by indirect electroreduction catalyzed by a nickel(II) complex, proceeded with modest selectivity for formation of the Z(methylene)cyclopentanes.

Intramolecular N-(Acyloxy)iminium Ion-Alkyne Cycloadditions. A New Route to Bicyclic α-Amino Ketones

The intramolecular cyclocondensation of 15 cyclic N-(acyloxy)iminium cations containing tethered alkyne and alkene nucleophiles is reported (eqs 5 and 6).This route to heterotricyclic systems was specifically demonstrated with substrates in which the hete
