The thiol-ene coupling (TEC) reaction has attracted a lot of scientific attention during the last years, particularly in the fields of polymers, materials and more recently in drug design. The combination of organocatalysis and photocatalysis has enabled the development of an efficient synergistic protocol for the addition of various thiols to a plethora of olefins. Utilizing phenylglyoxylic acid as the catalyst-initiator and common household bulbs as the light source, we report an organocatalytic photoinitiated TEC reaction showing exceptional tolerance in the presence of various functionalities, untangling previously unsolved problems.

Novel (E)-3,4-dihydroxystyryl aralkyl sulfones and sulfoxides were designed and synthesized as new analogues of 1, which showed interesting multifunctional neuroprotective effects, including antioxidative and antineuroinflammatory properties. Specifically, target compounds display excellent potency in scavenging reactive free radicals and demonstrate potent effects against various kinds of toxicities, including H2O2, 6-hydroxydopamine, and lipopolysaccharide in different types of neuronal cells. The antioxidative properties of the target compounds are more potent than that of 1, and the antineuroinflammatory properties are less strong than that of 1. According to the parallel artificial membrane permeation assay for the blood-brain barrier, target compounds possess greater blood-brain barrier (BBB) permeability than 1. In short, due to improvement of the antioxidative effect, stability, and BBB permeability, (E)-3,4-dihydroxystyryl aralkyl sulfones and sulfoxides can thus be considered as potential multifunctional neuroprotective agents and serve as new lead candidates in the treatment of neurodegenerative diseases.

The condensation of 2-phenylethanesulfonylacetic acid (4) with araldehydes (5) in presence of a base gave E-styryl-2-phenylethyl sulfones (6) which on dehydrogenation with DDQ (7) yielded E,E-bis-(styryl)sulfones (8). The 8 on treatment with dichlorotris(triphenyl-phosphine)ruthehium(II) catalyst resulted 1,4-diaryl-1,3-butadienes (9). The configurations of 6, 8 and 9 have been determined based on IR and 1H NMR spectral data.
