Photoexcited acetophenone can catalyze the fluorination of unactivatedC(sp(3))-H groups. While acetophenone, a colorless oil, only has a trace amount of absorption in the visiblelight region, its photoexcitation can be achieved by irradiation with light generated by a household compact fluorescent lamp (CFL). This operational simple method provides improved substrate scope for the direct incorporation
A group effort: Reported is the title reaction using a polycomponent catalytic system involving commercially available Selectfluor, a putative radical precursor N‐hydroxyphthalimide, an anionic phase‐transfer catalyst (KB(C6F5)4), and a copper(I) bis(imine). The catalyst system formed leads to monofluorinated compounds selectively (see example) without the necessity for an excess of the alkane substrate
共同努力:报告为使用多组分催化体系的标题反应,涉及可商购的Selectfluor,推定的自由基前体N-羟基邻苯二甲酰亚胺,阴离子相转移催化剂(KB(C 6 F 5)4)和铜(I)二(亚胺)。形成的催化剂体系选择性地产生单氟化化合物(参见实施例),而无需过量的烷烃底物。

The present invention provides compounds, pharmaceutically acceptable compositions thereof, and methods of using the same for the modulation of one or more SWI/SNF-related matrix associated actin dependent regulator of chromatin subfamily A (SMARCA) and/or polybromo-1 (PB-1) protein via ubiqitination and/or degradation by compounds. The compounds are bifunctional molecules that link a cereblon-binding moiety to a ligand that binds SMARCA and/or PB1 proteins.
