General description
Chiral urea compounds catalyzed hetero-Michael addition reaction of 2(5H)-furanone (γ-crotonolactone) to pyrrolidine. The quorum sensing inhibition activity by 2(5H)-furanone was studied using bioindicator strains.
Application
2(5H)-Furanone (γ-Crotonolactone) has been used in:
- synthesis of (+)-L-733,060, (+)-CP-99,994 and (2S,3R)-3-hydroxypipecolic acid
- synthesis of 5-substituted 2(5H) furanones (γ-butenolides) via direct aldol reaction with aromatic aldehydes catalyzed by bifunctional aminothiourea and aminosquaramide organocatalysts
- Michael addition reactions for synthesis of lignans
- three-component Michael-Aldol reactions with an aldehyde anda thiolate or carbanion

Chiral urea compounds 10a-g were synthesized as catalysts for conjugate addition of pyrrolidine (2) to gamma-crotonolactone (3). In the presence of a catalytic amount of the chiral ureas, this hetero-Michael reaction was greatly accelerated. Asymmetric induction was observed with the
