The use of nickel complexes in chain-walking strategies has recently gained considerable momentum owing to their versatility for forging sp3 architectures and their redox promiscuity that facilitates both one-electron or two-electron reaction manifolds. This Review discusses the relevance and impact that these processes might have in synthetic endeavours, including mechanistic considerations when appropriate. Particular emphasis is given to the latest discoveries that leverage the potential of Ni-catalysed chain-walking scenarios for tackling transformations that would otherwise be difficult to accomplish, including the merger of chain-walking with other new approaches such as photoredox catalysis or electrochemical activation. Ni-catalysed chain-walking blossomed as an effective synthetic tool to functionalize C(sp3)–H bonds in hydrocarbon chains. This Review provides a detailed overview of the most recent advances in this field, focusing on site-selective and regioselective manipulations at previously out-of-reach C(sp3)–H sites.","PeriodicalId":18849,"journal":{"name":"Nature reviews.

Proteins and nucleic acids have sustained evolution and life for billions of years, but both are condensation polymers, suggesting that their formation requires the elimination of water. This presents intrinsic challenges at the origins of life, including how condensation polymer synthesis can overcome the thermodynamic pressure of hydrolysis in water and how nucleophiles can kinetically outcompete water to yield condensation products. The answers to these questions lie in balancing thermodynamic activation and kinetic stability. For peptides, an effective strategy is to directly harness the energy trapped in prebiotic molecules, such as nitriles, and avoid the formation of fully hydrolysed monomers. In this Review, we discuss how chemical energy can be built into precursors, retained, and released selectively for polymer synthesis. Looking to the future, the outstanding goals include how nucleic acids can be synthesized, avoiding the formation of fully hydrolysed monomers and what caused information to flow from nucleic acids to proteins. Water is essential for life but paradoxically considered detrimental to the origins of life. Here, we discuss whether avoiding hydrolysed monomers and exploiting the chemical energy in prebiotic precursors may hold the missing key to unlocking biopolymer synthesis.","PeriodicalId":18849,"journal":{"name":"Nature reviews.

In the context of retrosynthetic analysis, the concept of molecular complexity is central to identifying productive disconnections and the development of efficient total syntheses. However, this field-defining concept is frequently invoked on an intuitive basis without precise definition or appreciation of its subtleties. Methods for quantifying molecular complexity could prove useful for characterizing the state of synthesis in a more rigorous, reliable and reproducible fashion. As a first step to evaluating the importance of these methods to the state of the field, here we present our perspective on the development of molecular complexity quantification and its implications for chemical synthesis. The extension and application of these methods beyond computer-aided synthesis planning and medicinal chemistry to the traditional practice of ‘complex molecule’ synthesis could have the potential to unearth new opportunities and more efficient approaches for synthesis. Quantifying molecular complexity has the potential to enhance retrosynthetic analysis and, thus, aid the development of efficient total syntheses. This Perspective discusses methods for rigorous, reproducible complexity measurement, highlighting their potential to revolutionize traditional complex molecule synthesis and uncover new synthetic opportunities.","PeriodicalId":18849,"journal":{"name":"Nature reviews.
