Descrição geral
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.
Aplicação
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
