Correction to A Rapid, One-Pot, Microwave-Influenced
Synthesis of Spiro-2,5-diketopiperazines via a Cascade
Ugi/6-Exo-Trig Aza-Michael Reaction [The Journal of
Organic Chemistry J. Org. Chem. 2011, 76, 2261ꢀ2264. DOI:
10.1021/jo102305q]. Soumava Santra, and Peter R. Andreana*
Page 2263. There is an error on line 3 of the continuing
paragraph as it should read “...with microwave irradiation 500
isomerizes to 5000 due to a low...” and not as it is currently written.
Furthermore, in Scheme 1, compound 3a is missing a carbonyl.
Scheme 1.
Relative stereochemistry (dashed/solid wedges) has been added
to compounds 5a, 6a, and 50 (Scheme 2) and compounds 6f,g
and 7a,b.
Scheme 2.
Also in reference 23b there should be an A. after Loupy.
