A Photoredox Catalysis Approach for the Synthesis of Both the ABDE and the ABCD Cores of Tronocarpine

A general strategy for the facile construction of both the ABDE and ABCD cores of tronocarpine, chippiine and dippinine alkaloids through the retrosynthetic disconnection of the polycyclic motifs into an indole or tryptamine fragment and a suitably functionalized alkyl chain is presented. The approach is enabled by an efficient Ir(III)-catalyzed, photoredox-mediated radical addition of tetramethyl 1-bromopentane-1,1,3,5-tetracarboxylate and dimethyl 2-bromopentanedioate selectively at C-2 of the indole. Subsequent intramolecular cyclization events furnish the desired ABDE and ABCD polycyclic cores in good preparative yields.

POLYVALENT ESTER COMPOSITION AND MANUFACTURING METHOD THEREFOR

PROBLEM TO BE SOLVED: To provide a composition having high compatibility with an acryl resin, capable of improving bending property when used for an acryl resin film, excellent in handleability, less in breed out, having nonvolatility or low volatility, environmentally friendly and capable of being used as a plasticizer. SOLUTION: There is provided a polyvalent ester composition containing a compound represented by the formula (1) and having percentage of a compound where total of x and y is 3 of 30 to 99 mol% based on 100 mol% of the compound represented by the formula (1), the polyvalent ester compound and a manufacturing method therefor including a process of reacting acrylic acid ester, an active methylene compound and methylene glutaric acid diester. In general formula (1), A is each independently CN, COCH3 or COOX, B is COOX, X is each independently H, a C1 to 20 substituted or unsubstituted alkyl group and x and y are each independently the number of 0 to 10.
