Regioselective construction of polysubstituted pyridine ring from Baylis–Hillman adducts via sequential introduction of tosylamide, Michael reaction, aldol condensation, and elimination of TsH

Synthesis of novel ferrocenyl N/O-heterocycles, chiral P,N-ligand and α-dehydro-β-amino acid derived short peptides from Morita–Baylis–Hillman adducts of ferrocenealdehyde

The golden triangle of Fc, OH/NH, COO moieties created by classical/aza-MBH reaction of ferrocenealdehyde has been exploited for the first time for the synthesis of the title compounds.

One-Pot Synthesis of New Type Aza- Baylis–Hillman Adducts from Chlorovinyl Aldehydes under Solvent-Free Condition

A series of new type aza- Baylis–Hillman adducts were prepared in moderate yields by one-pot treatment of chlorovinyl aldehydes, benzenesulfonamides and activated olefins under solvent-free condition. The chlorovinyl aldehydes were obtained via chloroformylation of ketones using bis(trichloromethyl)carbonate(BTC)/DMF system.

Ultrasound-promoted access to Baylis-Hillman amines

It is surveyed that the amination of the Baylis-Hillman acetates with primary amines can be dramatically promoted in improved yields and shortened reaction time under ultrasound irradiation than those under conventional stirring. The extensive scope of both amines and acetates are screened to investigate the relationship between substituents and their performance in such transformation.
