An economical, solvent-free, and metal-free method for peptidesynthesis via C–N bond cleavage using lactams has been developed. The method not only eliminates the need for condensation agents and their auxiliaries, which are essential for conventional peptidesynthesis, but also exhibits high atom economy. The reaction is versatile because it can tolerate side chains bearing a range of functional
A method of producing a polypeptide compound, wherein a peptide compound represented by formula (P) is obtained by inducing an amide formation reaction between an amino-protected lactam compound represented by formula (R1) and an amino acid ester or peptide ester compound represented by formula (R2).
The definitions for the reference signs in formulae (R1), (R2), and (P) are as set forth in the claims.
Hydrogenation of N-Acylcarbamates and N-Acylsulfonamides Catalyzed by a Bifunctional [Cp*Ru(PN)] Complex
Awakening of the Cp one: The bifunctionalcomplex 1 facilitates the interaction with substrates bearing less electrophilic carbon atoms than ketones, epoxides, and imides. The title reaction was applicable to the reduction of Evans' asymmetric alkylation products to the chiral alcohols along with good recovery of the chiral oxazolidinone auxiliary. EWG=electron‐withdrawing group.
