Diaryl-3-(5,5-dimethyl-3-hydroxy-2-cyclohexene-1-one-2-yl)-1-acetones have been synthesized in good yields by the Michael addition reaction of 5,5-dimethyl-1,3-cyclohexanedione (dimedone) with 1,3-diaryl-2-propen-1-one (chalcone) in DMF catalyzed by KF/Al 2O 3.

Via C-2 and C-6 hydroxyl group of β-cyclodextrin(CD) were functionally modified respectively,the AB2 type β-CD functional monomer with Si-H and double bonds was synthesized by hydrosilylation and Michael addition reaction,and the molecular structure of the functional monomer was characterized with 1H NMR,MALDI-TOF MS and element analysis.

A lower generation dendritic compound was synthesized from ethylenediamine and iso-octyl acrylate by Michael addition in methanol without catalyst.

3- Methyl-3-(1′-nitroethyl)-4-ethoxycarbonylcyclohexanone(Ⅰ) was synthesized through the Michael addition of Hagemann′s ethylester with nitroethane catalyzed by different bases.

A novel type of photocurable resin was sythesis through Michael addition of acrylate containing polybasic double bond such as TMPTA with polybasic aliphatic amine such as ethylenediamine and triethylenetetraamine,which was characterizaled by 1HNMR,FT-IR,GPC and UV-curable experment.

Afterthen,a kind of injectable hydrogels was prepared via Michael-type addition reaction of dithiothreitol with this macromer.

A kind of novel three-dimensional crosslinked hydrogel was synthesized via Michael-type addition reaction of dithiothreitol (DTT) as a crosslinker towards the self-assembly of α-CDs with three-arm acryloyl end-capped PEG.
