Abstract
A new metal-free method for the synthesis of selenoesters directly from carboxylic acids in a flow reactor is reported. The carboxylic acids, Michael acceptors, and bifunctional selenoureas (source of selenium and nucleophile, activator of carbonyl group) were reacted to obtain selenoesters (up to 70% yield). An evidence-backed plausible mechanism is also presented.

Abstract
Synthesis of novel homoazanucleosides and their peptidyl analogs as hybrid molecules comprised of amino acids, an iminosugar and natural nucleobases is reported for the first time. A pluripotent amino-substituted chiral polyhydroxypyrrolidine, possessing orthogonally different functional groups on either arm of the pyrrolidine ring, served as an ideal substrate for the synthesis of the proposed peptidyl homoazanucleosides. The acid sensitive primary benzyloxy group, on one arm of the pyrrolidine ring, after selective deprotection, was utilized for the introduction of nucleobases to obtain the homoazanucleosides. The amino group on the other side offered the opportunity to be coupled with amino acids to deliver the desired peptidyl homoazanucleosides. Glycosidase inhibition studies revealed that the acetamido derivatives of homoazanucleosides were found to be sub-millimolar inhibitors of β-N-acetyl-glucosaminidase.

Abstract
The present review offers an overview of nonclassical (e.g., with no pre- or in situ activation of a carboxylic acid partner) approaches for the construction of amide bonds. The review aims to comprehensively discuss relevant work, which was mainly done in the field in the last 20 years. Organization of the data follows a subdivision according to substrate classes: catalytic direct formation of amides from carboxylic and amines ( section 2 ); the use of carboxylic acid surrogates ( section 3 ); and the use of amine surrogates ( section 4 ). The ligation strategies (NCL, Staudinger, KAHA, KATs, etc.) that could involve both carboxylic acid and amine surrogates are treated separately in section 5 .

Abstract
The chemical synthesis of peptides or small proteins is often an important step in many research projects and has stimulated the development of numerous chemical methodologies. The aim of this review is to give a substantial overview of the solid phase methods developed for the production or purification of polypeptides. The solid phase peptide synthesis (SPPS) technique has facilitated considerably the access to short peptides (<50 amino acids). However, its limitations for producing large homogeneous peptides have stimulated the development of solid phase covalent or non-covalent capture purification methods. The power of the native chemical ligation (NCL) reaction for protein synthesis in aqueous solution has also been adapted to the solid phase by the combination of novel linker technologies, cysteine protection strategies and thioester or N,S-acyl shift thioester surrogate chemistries. This review details pioneering studies and the most recent publications related to the solid phase chemical synthesis of large peptides and proteins.
