The present disclosure relates to bifunctional compounds, ULM— L—PTM, 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.

Herein, we report the photocatalytic decarboxylative alkenylation reactions of N-(acyloxy)phthalimide derived from α-amino and α-hydroxy acids with 1,1-diarylethene, and with cinnamic acid derivatives through double decarboxylation, using sodium iodide and triphenylphosphine as redox catalysts. The reaction proceeds under mild irradiation conditions with visible blue light (440 nm or 456 nm) in an

The present disclosure relates to bifunctional compounds, which find utility as modulators of estrogen receptor (target protein). In particular, the present disclosure is directed to bifunctional compounds, which contain on one end at least one of a Von Hippel-Lindau ligand, a cereblon ligand, Inhibitors of Apoptosis Proteins ligand, mouse double-minute homolog 2 ligand, or a combination thereof, which binds to the respective E3 ubiquitin ligase, and on the other end a moiety which binds the target protein, 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.

Construction of Vicinal Tetrasubstituted Stereogenic Centers<i>via</i>a Mannich-Type Organocatalyzed Addition of Δ<sup>2</sup>-Pyrrolin-4-ones to Isatin Imines
Mannich‐type addition to isatin‐derived ketimines to furnish the non‐racemic oxindole‐Δ2‐pyrrolin‐4‐one adducts, stereoselectively (up to 96% ee, dr≥15:1). The oxindole–pyrrolone products feature vicinaltetrasubstituted carbon stereocenters. The developed protocol has a broad substrate scope and tolerates diverse substituents at position C‐5 in 4‐pyrrolones and at positions N‐1 and C‐5/7 in isatin imines
