Visible-Light-Mediated Regioselective Chlorosulfonylation of Acrylamides [PDF]

open access: yes, 2023
Herein, a one-step chlorosulfonylation of acrylamides via a photocatalytic redox process is described. This reaction provides ?-chlorosulfonylamides with a quaternary center with high regioselectivity via radical process.

Stereoselective intermolecular radical cascade reactions of tryptophans or ɤ-alkenyl-α-amino acids with acrylamides via photoredox catalysis

open access: yesNature Communications, 2022
Photocatalytic radical cascade reactions enable the facile construction of diverse cyclic compounds, though they rely on templated precursors. In this paper, the authors report on stereoselective intermolecular radical cascade reaction between tryptophan

Acrylamide poisoning [PDF]

open access: yesPostgraduate Medical Journal, 1977
SummaryA small epidemic of acrylamide poisoning amongst workers in the construction industry is described. The clinical features of this condition are reviewed and two cases are described in which residual neurological problems persisted for over 1 year. The literature on acrylamide poisoning is reviewed and it is recommended that this substance should

Reactivity of Acrylamides Causes Cytotoxicity and Activates Oxidative Stress Response

open access: yes, 2023
Acrylamides are widely used industrial chemicals that cause adverse effects in humans or animals, such as carcinogenicity or neurotoxicity. The excess toxicity of these reactive electrophilic chemicals is especially interesting, as it is mostly triggered
