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

The construction of carboxylic acid compounds in a selective fashion from low value materials such as alkenes remains a long-standing challenge to synthetic chemists. In particular, β-addition to styrenes is underdeveloped. Herein we report a new electrosynthetic approach to the selective hydrocarboxylation of alkenes that overcomes the limitations of current transition metal and photochemical approaches. The reported method allows unprecedented direct access to carboxylic acids derived from β,β-trisubstituted alkenes, in a highly regioselective manner.

Paragraph 0035-0038, (2019/03/08)
The invention discloses a preparation method of a tetrahydroisoquinoline derivative. The tetrahydroisoquinoline derivative is prepared by subjecting 1-(tetrapyrrolidin-1-yl)-1,2,3,4-tetrahydroisoquinoline and 2,3-dihydro-indene-3-one-1-carboxylic acid to condensation. Process conditions are optimized so that preparation steps are simplified. Agents used in the preparation are pollution free. The prepared tetrahydroisoquinoline derivative 1-(tetrapyrrolidin-1-methyl)-2-(2,3-dihydro-indene-3-one-1-carbonyl)-1,2,3,4-tetrahydroisoquinoline can provide good calming effect against neuropathic pain.The tetrahydroisoquinoline derivative has high medical value in drug compositions for pain treatment and in replacing dependent analgesics, such as morphine.
