Photoredox Activation of Formate Salts: Hydrocarboxylation of Alkenes via Carboxyl Group Transfer

A photoredox activation mode of formate salts for carboxylation was developed. Using a formate salt as the reductant, carbonyl source, and hydrogen atom transfer reagent, a wide range of alkenes can be converted into acid products via a carboxyl group tra

Synthesis method of succinic acid derivative or 3 -arylpropionic acid (by machine translation)

The invention discloses a synthesis method of a succinic acid derivative or 3 -arylpropionic acid, which comprises the following steps: adding a base in a drying reaction tube and CO removing CO. 2 The reaction is carried out under the irradiation of visible light, the reaction is carried out under visible light irradiation, and then separation and purification are carried out to obtain the butanedioic acid derivative or 3 -arylpropionic acid product; the base comprises sodium tert-butoxide, potassium tert-butoxide, lithium tert-butyl alcohol and 4 - potassium carbonate; and the reaction substrate comprises an acrylate compound or an aryl vinyl compound. CO can be induced by visible light. 2 The scheme provided by the invention is mild in reaction condition and wide in reaction 3 - substrate selectivity, and the reaction substrate is wide in selectivity, the raw materials are cheap and easily available, and the method has a good industrial application prospect.

Neuroleptic activity and dopamine-uptake inhibition in 1-piperazino-3-phenylindans

A series of 1-piperazino-3-phenylindans was synthesized and tested for neuroleptic and thymoleptic activity. Neuroleptic activity was found only in trans racemates and was associated with one of the enantiomers only. The potent and long-acting neuroleptic compound trans-4-[3-(4-fluorophenyl)-6-(trifluoromethyl)indan-1-yl]-1-piperazineeth anol (Lu 18-012, tefludazine) was developed by systematic variation of structural components. Thymoleptic activity was optimized, especially with respect to dopamine-uptake inhibition. No geometrical stereoselectivity was found with regard to dopamine-uptake inhibition, but a high enantioselectivity could be demonstrated for both cis and trans racemates. The most potent compounds were 1-piperazino-3-(3,4-dichlorophenyl)indans with IC50 values of about 2 nM for inhibition of dopamine uptake.
