Abstract: Abstract The reaction of (2 S ,3 S ,4 R )-2,3,4,7-tetrahydroxy-6-oxoheptanals with lower alcohols produced protected 3-deoxy- d - arabino -2-heptulosonates. The key transformation is based on an 1,4-O–O silyl group migration, followed by 6-…

Abstract: In the present work, the synthesis of acetylated salicins, which occur naturally in many Salicaceae species, is reported. The preparation of 2-O-acetylsalicin, 2-O-acetylchlorosalicin, and 2-O-acetylethylsalicin from peracetylated bromosalicin with selective acid-catalyzed deacetylation and one-pot nucleophilic…

Abstract: Synthetic [Fe4S4] clusters with Fe-R groups (R = alkyl/benzyl) are shown to release organic radicals on an [Fe4S4]3+-R/[Fe4S4]2+ redox couple, the same that has been proposed for a radical-generating intermediate in the superfamily of radical…

Abstract: In this study, we report substituent effect on aryl group migration in (para-C6H4X)Mn(CO)5 complexes using mpw1pw91 quantum chemical calculations. These calculations reveal good linear relationships between barrier energy (ΔE), activation energy (ΔH‡), activation free energy…

Abstract: Coordination of diverse individuals often requires sophisticated communications and high-order computational abilities. Microbial populations can exhibit diverse individualistic behaviors, and yet can engage in collective migratory patterns with a spatially sorted arrangement of phenotypes. However,…
