In 2019,Organic Chemistry Frontiers included an article by Jiao, Meng-Jie; Liu, Dan; Hu, Xiu-Qin; Xu, Peng-Fei. Category: esters-buliding-blocks. The article was titled 《Photocatalytic decarboxylative [2+2+1] annulation of 1,6-enynes with N-hydroxyphthalimide esters for the synthesis of indene-containing polycyclic compounds》. The information in the text is summarized as follows:
An efficient photoredox-mediated [2+ 2+1] cascade annulation of 1,6-enynes with N-hydroxyphthalimide esters was reported for the synthesis of a series of indene-containing polycyclic frameworks such as I [R1 = t-Bu, Ph, 2-thienyl, etc.; R2 = H, 5-Me, 5-Cl, 5-F, 6-Cl; R3 = CN, CO2Me, CO2Bn; R4 = R5 = Me; R4R5 = (CH2)4, (CH2)2O(CH2)2, (CH2)2C(O)(CH2)2, etc.] through a sequence of radical addition, 5-exo-dig cyclization, 1,n-H shift and 5-endo-trig cyclization. This protocol exhibited excellent functional group tolerance for establishing spiro and non-spiro polycyclic architectures under mild conditions. Moreover, this transformation could also be achieved smoothly via a simple phosphine/iodide-based photoredox system.Benzyl acrylate(cas: 2495-35-4Category: esters-buliding-blocks) was used in this study.
Benzyl acrylate(cas: 2495-35-4) has been used in preparation of high refractive index polyacrylates. Benzyl acrylate is used in the preparation of heptanoic acid benzyl ester. It is used to prepare polybenzylacrylate using azobisisobutyronitrile as initiator.Category: esters-buliding-blocks
