Grass functional traits reflect the long history of fire and grazers in the savannas of Texas
Abstract Premise Understanding relationships among grass traits, fire, and herbivores may help improve conservation strategies for savannas that are threatened by novel disturbance regimes. Emerging theory, developed in Africa, emphasizes that functional traits of savanna grasses reflect the distinct ways that fire and grazers consume biomass ...

Survivorship of Individuals With Double Heterozygosity for Achondroplasia and Type 2 Collagenopathy
ABSTRACT Historically, double heterozygosity, or a diagnosis of two separate, dominant genetic conditions, was often thought to be lethal in individuals with autosomal dominant skeletal dysplasias. In previously published studies of individuals with dual dysplasia diagnoses of achondroplasia and type 2 collagenopathy, infants died of respiratory ...

Large‐Scale Chemoenzymatic Synthesis of a Glycophorin A Tetrasaccharide Motif and Its Analogues
A large‐scale chemoenzymatic method was developed to synthesize natural and modified analogues of the Glycophorin A tetrasaccharide with either C9 or C5 terminal α‐2,3‐sialic acid variants. Selective α‐2,6‐sialylation of galactosamine was achieved by maintaining acetylation of the galactose during the course of enzymatic reactions. The products can aid

A facile synthetic route to (−)‐8a‐epi‐lentiginosine from d‐glucose using the Pd‐BiPhePhos catalyzed intramolecular Tsuji–Trost reaction of non−derivatized allylic alcohol as a key construction of the hydroxylated pyrrolidine ring is reported. The crystal structure of (−)‐8a‐epi‐lentiginosne showed the envelope conformation of the five‐membered ring ...

An interrupted Barton–Zard reaction/Friedel–Crafts alkylation telescoped reaction provides aryl‐substituted pyrrolo[3,4‐b] cores in moderate‐to‐good yields as mostly single diastereomers. The reaction is tolerant of a wide range of electron‐deficient indoles and (hetero)aromatic nucleophiles, offering a modular approach for the synthesis of multi ...
