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。

studies that, to our surprise, was revealed to be a radical chain mechanism in which copper acts as an initiator. Furthermore, we offer an explanation for the notable but curious preference for monofluorination by ascribing an ionic character to the transition state.

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.
