The invention relates a method for preparation of betulonic acid or betulinic acid from betulin wherein the method comprises a stage for oxidizing betulin to betulonic aldehyde and/or betulinic aldehyde with Pd(ll)-catalyst catalyzed oxidation process in the presence of dioxygen.
malonates to in situ generated N-formylimines of aromatic aldehydes was achieved underphase-transfercatalysis using Cinchona alkaloids-derived quaternaryammoniumsalts. The resulting β-formamidomalonates have been efficiently converted into β-aryl-β-isocyano esters. Their utility in the multicomponent Ugi reaction with chiral cyclic imines has been demonstrated.

A novel gypsum board having improved antifungal properties is disclosed. The board comprises a gypsum core, front and back paper facings, and a polymeric antifungal agent effective at inhibiting fungal growth. A preferred polymeric antifungal agent is polyDADMAC or polyTMMC. The novel gypsum board further comprises a non-polymeric antifungal agent comprising a fluorine-containing quaternary ammonium compound. Preferred non-polymeric ammonium compounds include Tetra-n-butylammonium fluoride and Tetraethylammonium fluoride. The polymeric antifungal agent can be present in the gypsum core and/or on one or both of the paper facings. The non-polymeric antifungal agent may be encapsulated in a material or ionically associated with the polymeric antifungal agent to allow releases of the non-polymeric antifungal agent over time and/or upon exposure to moisture. Methods for preparing the aforementioned novel gypsum board are also disclosed.
