salt and oxone is reported. The preliminary mechanistic investigations suggest that the key factor for achieving the anti-Markovnikov regioselectivity is the semipinacol rearrangement of an iodo functionalized intermediate, which is confirmed by an isotope labeling experiment. In addition, the reaction involves the de-iodination of a co-iodo intermediate via its oxidation to hypervalent iodine species

Acetal derivatives are easily obtained from 1,2-difunctionalizedcompounds by a new reaction mediated by IPy2BF4 with a mechanism based on a 1,2-migration of aryl or alkyl groups. A new oxidative rearrangement reaction of olefins is also described. Moreover, when this metal-free protocol is applied to cyclic olefins, interesting ring-contraction reactions are observed. The new methodologies described
Highly Selective One-Pot Synthesis of Polysubstituted Isoflavanes using Styryl Ethers and Electron-Withdrawing ortho-Quinone Methides Generated In Situ
highly selective one-potsynthesis of polysubstituted isoflavanes has been developed. The reaction proceeds through the cycloaddition of methyl styryl ethers, derived from phenylacetaldehyde dimethyl acetals under acidic conditions, with electron-withdrawing ortho-quinone methides generated in situ. When phenylacetaldehyde dimethyl acetals were reacted with salicylaldehydes, the reaction proceeded smoothly

The present disclosure relates to bifunctional compounds, which find utility as modulators of Rapidly Accelerated Fibrosarcoma (RAF, such as c-RAF, A-RAF and/or B-RAF; the target protein). In particular, the present disclosure is directed to bifunctional compounds, which contain on one end a Von Hippel-Lindau, cereblon, Inhibitors of Apotosis Proteins or mouse double-minute homolog 2 ligand which binds to the respective E3 ubiquitin ligase and on the other end a moiety which binds the target protein RAF, such that the target protein is placed in proximity to the ubiquitin ligase to effect degradation (and inhibition) of target protein. The present disclosure exhibits a broad range of pharmacological activities associated with degradation/inhibition of target protein. Diseases or disorders that result from aggregation or accumulation of the target protein, or the constitutive activation of the target protein, are treated or prevented with compounds and compositions of the present disclosure.
本公开涉及双功能化合物,它们可用作快速加速纤维肉瘤(RAF,如c-RAF、A-RAF和/或B-RAF;靶蛋白)的调节剂。特别是,本公开内容涉及双功能化合物,其一端含有与相应 E3 泛素连接酶结合的 Von Hippel-Lindau、cereblon、抑制细胞凋亡蛋白或小鼠双敏同源物 2 配体,另一端含有与靶蛋白 RAF 结合的分子,从而将靶蛋白置于泛素连接酶附近,以实现对靶蛋白的降解(和抑制)。本公开物具有与降解/抑制靶蛋白相关的广泛药理活性。本公开的化合物和组合物可以治疗或预防由于靶蛋白的聚集或积聚或靶蛋白的组成性激活而导致的疾病或失调。
