We analyzed 15 bifunctional squaramides with benzyl-like fragments in a Michael addition. These substituents are susceptible to form CH⋯π interactions and have distinct properties: electronic features, a stereogenic center, as well as additional c

RNA‐catalyzed RNA ligation is widely believed to be a key reaction for primordial biology. However, since typical chemical routes towards activating RNA substrates are incompatible with ribozyme catalysis, it remains unclear how prebiotic systems g

Polymerization of nucleic acids in biology utilizes 5'-nucleoside triphosphates (NTPs) as substrates. The prebiotic availability of NTPs has been unresolved and other derivatives of nucleoside-monophosphates (NMPs) have been studied. However, this la

Phosphorylation of (pre)biotically relevant molecules in aqueous medium has recently been demonstrated using water-soluble diamidophosphate (DAP). Questions arise relating to the prebiotic availability of DAP and other amidophosphosphorus species on

We report an easy method to estimate relative hydrogen bond basicities of amides and imides in chloroform via 1H NMR experiments. We established hydrogen acceptor capacities of the studied compounds through their effect on the C H signal of the resid

Recent demonstrations of RNA-DNA chimeras (RDNA) enabling RNA and DNA replication, coupled with prebiotic co-synthesis of deoxyribo- and ribo-nucleotides, have resurrected the hypothesis of co-emergence of RNA and DNA. As further support, we show tha

The design of new catalysts usually involves the synthesis and experimental evaluation of many compounds. We report herein an alternative methodology for designing bifunctional organocatalysts based on electron density topological analyses, i.e. the
