Abstract: A high-molecular-weight polyester of poly(mandelate-co-lactate) (PML) is prepared by ring-opening polymerization of stereo-configuration controlled cyclic diester monomers of methyl-6-phenyl-1,4-dioxane-2,5-dione (MPDD) and lactide. The attained PML shows excellent glassy properties, although the original stereo-configuration of MPDD… read more here.

DOI: 10.1055/s-0037-1610110
Abstract: 2-Ethylquinazolin-4-one derivatives bearing various ortho-substituted phenyl groups were revealed to possess a stable C–N axially chiral structure at ambient temperature. The reactions of alkyl halides with the anionic species prepared from these quinazolinones were systematically… read more here.
