compounds, including racemic analogues of 1, dihydropyranones and C-acylated Meldrum's acid derivatives, the later obtained in one synthetic step from commercially available starting material. We further characterized the behavior of some representative compounds in aqueous solution and evaluated their in vitro PTPase binding and inhibition. Our data reveal that rac-1 and some derivatives are able to form

Bactobolins are complex inhibitors of protein synthesis that target a novel site of the bacterial ribosome. A simple synthetic process by which (−)-quinic acid, L-threonine and L-alanine are combined to yield (+)-actinobolin is reported. The modularity of the approach unlocks new possibilities in analog synthesis.
A Pd(II)-catalyzedasymmetric 1,6-addition of arylboronic acids to Meldrum's acid-derived dienes was developed. A new substituted In-Pyrox ligand was designed to enable this reaction with high enantioselectivity via a remote steric effect. A series of Meldrum's acid-derived dienes and arylboronic acids were tolerable to the reaction conditions, giving the desired adducts in moderate to high yields
