Crystal structure and Hirshfeld surface analysis of new polymorph of racemic 2-phenylbutyramide

Acta Crystallographica Section E: Crystallographic Communications, 2019
A new polymorph of the title compound, C10H13NO, was obtained by recrystallization of the commercial product from a water/ethanol mixture (1:1 v/v). Crystals of the previously reported racemic and homochiral forms of 2-phenylbutyramide were grown from ...

Clinical advances in racemic epinephrine for pediatric croup: a mini-review of evidence and practice

Frontiers in Pediatrics
This mini-review critically evaluates the contemporary evidence regarding racemic epinephrine's role in pediatric croup management. As the pharmacological mainstay for acute airway obstruction, racemic epinephrine demonstrates rapid efficacy through dual

SkelPy: A graphic user interface–based approach for skeletonizing fungal networks

Applications in Plant Sciences, EarlyView.
Abstract Premise Traditional methods to quantify mycelial growth rely on destructive sampling to quantify biomass. Moreover, these approaches limit continuous observation and require a sufficient mass to measure. Recent work examines hyphal network traits by reconstructing the hyphal network from spatial coordinates via images, providing information ...

Racemic epinephrine compared to salbutamol in hospitalized young children with bronchiolitis; a randomized controlled clinical trial [ISRCTN46561076]

BMC Pediatrics, 2005
Background Bronchiolitis is the most common cause of lower respiratory tract illness in infancy, and hospital admission rates appear to be increasing in Canada and the United States. Inhaled beta agonists offer only modest short-term improvement.

One‐Pot Ruthenium‐Catalyzed Synthesis of Benzyl/Allyl‐Halide Substituted (dihydro)naphthalenes via Radical Benzannulation

ChemistryEurope, EarlyView.
A one‐pot protocol to synthesize reactive benzyl‐ and allyl‐halide‐substituted (dihydro)naphthalenes from 2,3‐aryl‐1,3‐butadiene substrates and halogenated alkanes has been developed, using [Cp*RuCl(PPh3)2] as the catalyst. Mechanistic studies revealed an atom transfer radical addition and radical benzannulation sequence, followed by HCl elimination ...

Enantioselective Synthesis of Sulfinamidines via Asymmetric Rhodium–Catalyzed Imidation of Sulfenamides

ChemistryEurope, EarlyView.
In this work, a catalytic enantioselective imidation approach is presented for the preparation of enantioenriched sulfinamidines from sulfenamides, employing a chiral dirhodium(II) tetracarboxylate catalyst. This method enables the imidation of N,N‐bisalkyl sulfenamides in yields of up to 98% and enantiomeric ratios up to 98:2, with a catalyst loading ...

Effects of Chirality on the Antifungal Potency of Methylated Succinimides Obtained by Aspergillus fumigatus Biotransformations. Comparison with Racemic Ones

Molecules, 2013
Eighteen (3R) and (3R,4R)-N-phenyl-, N-phenylalkyl and N-arylsuccinimides were prepared with high enantioselectivity by biotransformation of maleimides with A. fumigatus.

Cause of Chirality Consensus

, 2009
Biological macromolecules, proteins and nucleic acids are composed exclusively of chirally pure monomers. The chirality consensus appears vital for life and it has even been considered as a prerequisite of life.
