Abstract: Herein, we report the studies of the multicomponent reaction of 5-hydroxy-2-methyl-4H-pyran-4-one with carbonyl compounds and Meldrum's acid. General methods for the synthesis of 6-methyl-3,4-dihydropyrano[3,2-b]pyran-2,8-diones, 3-(3-hydroxy-6-methyl-4-oxo-4H-pyran-2-yl)propanoic acid amides and esters, as well as 7-oxo-7H-furo[3,2-b]pyran-3-ylacetic acids were… read more here.

Abstract: A highly efficient method for the enantioselective build of spiro[1-indanone-5,2'-γ-butyrolactones] has been developed through the tandem Michael/transesterification reaction of α-hydroxy-1-indanone and α,β-unsaturated esters. A broad range of spiro(1-indanone-butyrolacones) with contiguous stereocenters have been synthesized with… read more here.

DOI: 10.1134/s0036023618020110
Abstract: A new approach to the preparation of boron-containing siloxanes based on cluster boron anions has been suggested. This approach consists in the reaction of hydroxy derivatives of closo-decaborate anion [B10H10–n(OH)n]2– (n = 1, 2) with… read more here.

Abstract: Three-component reaction of 4-hydroxy-6-methylpyran-1-one with aromatic aldehydes and cyclic-1,3-diketone catalyzed by ZnO nanoparticles under solvent-free conditions leads a simple and efficient one-pot synthesis of pyrano[4,3-b]chromene-1,9-dione derivatives with high yields. The method has other advantages such… read more here.
