The synthesis and application of a newly designed C2-sym. chiral-substituted 1,16-dihedroxytetraphenylene (DHTP) is reported. Efficient syntheses of enantiopure substituted DHTP were accomplished, and these enantiopure compounds were used as organocatalysts in asym. allylboration of ketones under very mild conditions. Accordingly, several tertiary alcs. were generated in moderate to good yields with up to 99% ee by using the catalyst (S)-2,15-Br2-DHTP. A gram-scale reaction was achieved in 99% yield with 96% ee. In the experiment, the researchers used many compounds, for example, 1-Thiophen-2-yl-ethanone(cas: 88-15-3Recommanded Product: 1-Thiophen-2-yl-ethanone)
1-Thiophen-2-yl-ethanone(cas: 88-15-3) belongs to thiophenes. Reflecting their high stabilities, thiophenes arise from many reactions involving sulfur sources and hydrocarbons, especially unsaturated ones. Thiophenes are classically prepared by the reaction of 1,4-diketones, diesters, or dicarboxylates with sulfidizing reagents such as P4S10 such as in the Paal-Knorr thiophene synthesis.
