Low emission epoxy resin composition
-
Paragraph 0224-0229, (2021/09/01)
An epoxy resin composition, the curing components of which contain at least one amine of formula (I) and optionally at least one amine A which is, in particular, an adduct of a polyamine and an epoxide. The amine for formula (I) is used in particular in the form of a reaction product of the reductive alkylation of 1,2-ethylenediamine and an aldehyde or ketone. The epoxy resin composition is used in particular as a low-emission, room-temperature-curing epoxy-resin coating. It is characterised by good processibility, quick curing, high hardness, a nice surface and a low tendency to yellowing.

Highly enantioselective catalytic asymmetric intramolecular cascade imidization-nucleophilic addition-lactamization of N1-alkylethane-1,2-diamine with methyl 2-formylbenzoate catalyzed by a chiral phosphoric acid represents the first efficient method for the preparation of medicinally interesting chiral 2,3-dihydro-1H-imidazo[2,1-a]isoindol-5(9bH)-ones with high yields and excellent enantioselectivities. This strategy has been shown to be quite general toward various methyl 2-formylbenzoates.
