A reductive radical relay strategy for the construction of fused benzo[e]isoindole-1,3,5-trione through a reaction of α-bromo ketones with maleimides in the presence of Ir(ppy)3 under visible-light irradiation is described. The protocol employs very mild reaction conditions and offers satisfactory yields. Moreover, the reaction proceeds through a cascade C(sp3)-Br/C(sp2)-H functionalization, double C-C bond formation, and oxidative aromatization sequence.

A simple and efficient, Lewis acid catalysed reductive etherification strategy for the stereoselective synthesis of cis-2,6- disubstituted morpholines and 1,4-oxathianes starting from readily available 1,5-diketones has been developed. The strategy is used in the total synthesis of morpholine-based natural products (±)-chelonin A and formal total synthesis of (±)-chelonin C.
