A new convenient strategy for the synthesis of 3-hydroxy-2-pyrrolidinone derivatives featuring regioselective C–C coupling has been developed. This is a Cu (II) catalyzed cross dehydrogenative coupling (CDC) involving enamino-ketones of benzyl amines and di-alkyl acetylenedicarboxylate, followed by cyclization by primary amines. TBHP (tert-butyl hydroperoxide) has been used as the oxidant to promote the coupling protocol. This synthetic route principally demonstrates the scope of CDC reaction and also applicable to gram-scale synthesis.
Diels-Alder construction of regiodifferentiated meta-amino phenols and derivatives

Synthetic access to regiodifferentiated meta-amino phenols is described. The strategy relies upon distinct deprotonation conditions to afford regioisomeric thermodynamic and kinetic dienes that undergo a tandem Diels-Alder and retro-Diels-Alder sequence with assorted acetylenic dienophiles to afford a range of aromatic products.

A simple and efficient method to synthesize a variety of tetrahydroquinolinones was successfully achieved by reacting various β-enaminones with several α,β-unsaturated aldehydes. This strategy can be viewed as a Bronsted acid-mediated formal [3+3] cycloaddition. Springer-Verlag 2012.
Partially saturated indeno[1,2-b]indole derivatives via deoxygenation of heterocyclic α-hydroxy-N,O-hemiaminals
Hemmerling, Hans-Joerg,Reiss, Guido
experimental part, p. 985 - 999 (2009/12/01)
A series of 3-aminocyclohex-2-enones were reacted with indane-1,2,3-trione monohydrate (ninhydrin) yielding 4b,9b-dihydroxyindeno[ 1,2-b]indoles that were deoxygenated to indeno[1,2-b]indoles. Georg Thieme Verlag Stuttgart.
