The meroterpenoids fornicin A, D, and ganodercin found in mushrooms of the Ganoderma genus, have been prepared a concise divergent synthesis route. characteristic unsaturated γ-ketoacid moiety was obtained via an optimized step-wise aldol condensation between two readily accessible building blocks. THP-protection phenolic hydroxyl group under basic conditions developed, protocol that adds to ve...

An exceptionally stereoselective and general synthesis of (Z)-α-haloacrylates, ready to undergo various synthetic transformations, has been demonstrated from α-haloacetates and aldehydes in a one-pot manner via the titanium-enolate based asymmetric aldol condensation. Besides being an expedient synthetic procedure, the ready availability of diverse α-haloacetates, exceptional stereoselectivity,...

The self-aldol condensation of aldehydes was investigated with rare-earth cations stabilized by [Si]Beta zeolites in parallel bulk metal oxides. Good catalytic performance achieved all Lewis acidic and yttrium appeared to be the best choice. According results several complementary techniques, i.e., temperature-programmed surface reactions, situ diffuse reflectance infrared Fourier transform spe...
