PROTAC-mediated crosstalk between E3 ligases

Small-molecule heterobifunctional degraders can effectively control protein levels and are useful research tools. We assembled proteolysis targeting chimeras (PROTACs) from a cereblon (CRBN) and a von-Hippel-Lindau (VHL) ligase ligand and demonstrated a PROTAC-induced heterodimerization of the two E3 ligases leading to unidirectional and efficient degradation of CRBN.

Domino Reactions of Bis-Diazo Compounds: Rhodium(II) Acetate Catalyzed Diastereoselective Synthesis of Epoxy- and Epithio-Bridged Heterocycle-Fused Quinolizinone Analogues

Rhodium(II) acetate catalyzed domino reactions of bis-diazo compounds afford epoxy- and epithio-bridged heterocycle-fused quinolizinone systems in a stereoselective manner. The presence of an acceptor diazo functionality leads to a selective intermolecular X-H insertion reaction in a chemoselective manner, and the acceptor/acceptor diazo functionality subsequently participates in the formation of isomünchnone/thioisomünchnone 1,3-dipoles followed by intramolecular cycloaddition in a diastereoselective manner. This domino reaction is capable of constructing epoxy- and epithio-bridged heterocycle-fused quinolizinone ring systems with four stereogenic centers. The Bronsted acid induced reactions of oxa-bridged tricyclic compounds furnish ring-opened alcohol products in a regioselective manner.

Competitive intramolecular aminolysis: Relative rates of 5-and 6-membered lactam ring closure

Methyl 4,5-diaminopentanoate (4,5-Dape Me) undergoes competitive intramolecular aminolysis to 5-aminomethyl-2-pyrrolidinone (L5) and 5-amino-2-piperidinone (L6) in dilute alkaline aqueous solution at 25°C. Use of this single compound provides an ideal case for assessing the relative rates of 5- and 6-membered lactam ring closure. Assessments are also made using the intramolecular aminolysis of pairs of compounds: methyl 2,4-diaminobutanoate (2,4-Dab Me) and methyl 2,5-diaminopentanoate (2,5-Dape Me); methyl 4-aminobutanoate (4-Ab Me) and methyl 5-aminopentanoate (5-Ape Me).

Novel synthesis of 5,11-dihydro-6H-pyrido[2,3-b]-[1,4]-benzodiazepin-6-ones and related studies (1)

5,11-Dihydro-6H-pyrido[2,3-b][1,4]benzodiazepin-6-one (1), a basic intermediate in the preparation of 11-α-aminoacetyl derivatives with important biological activities, has been obtained by a three-step synthesis starting from easily available isatoic anhydride and anhydro ornithine. Some model cyclisation reactions leading to 5-member ring derivatives 10 and 12 instead of 7-member ring analogues of 1, are reported. Easy transformations of the tetrahydro congener of 1, i.e. compound 4 into 19, which actually represents a tetrahedral intermediate in the transformation of 5 into 4, is noticed. Further rearrangement of 19 into spiro compounds 20, and return of the latter into 5 is described.
