Building Molecules by a Self‐Replicator That Catalyzes Acyl Hydrazone Formation
A self‐replicator efficiently catalyzes the formation of acyl hydrazone bonds between a set of different substrates. In addition to previously reported (bond‐breaking) catalytic activity, this renders the self‐replicator highly promiscuous, which is a good starting point for Darwinian experiments en route to de‐novo life.

(Poly)Borylated Species as Modern Reactive Groups toward Unusual Synthetic Applications
In this review, we spotlight recent breakthroughs in α‐polyboron‐substituted carbon‐centered intermediates (carbanion, carbocation, radical, and carbene) and polyborylated alkenes. By bridging fundamental reactivity with the application potential of these extraordinary species, we hope this review will serve as a roadmap for harnessing these unique ...

Novel one-pot process for the synthesis of ethyl 2-imino-4-methyl-2,3-dihydrothiazole-5-carboxylates [PDF]
A facile one-pot two-step process for the synthesis of ethyl 2-imino-4-methyl-2,3-dihydrothiazole-5-carboxylates via the cyclocondensation of ethyl 2-thiocyanatoacetoacetate with a variety of hydrazine and hydrazide derivatives has been ...

Organic solvent-free synthesis of sulfonyl hydrazides in water
An organic solvent-free synthesis of sulfonyl hydrazides has been achieved in water. The reactions of equimolar amount of sulfonyl chlorides and hydrazines afforded a series of substituted sulfonyl hydrazides at 60 °C for 1 h in water as a solvent in ...

Rapid Total Synthesis of DARPin pE59 and Barnase [PDF]
We report the convergent total synthesis of two proteins: DARPin pE59 and Bacillus amyloliquefaciens RNase (Barnase). Leveraging our recently developed fast-flow peptide-synthesis platform, we rapidly explored numerous conditions for the assembly of long

Chemistry in charge of biology! Simple low‐molecular‐weight gelators, with minor modifications in molecular structure, self‐assemble differently and can also co‐assemble when simultaneously triggered. This creates a family of gels with different properties that direct the growth of stem cells in different ways.

Synthesis and Antioxidant Activity of Some New Coumarinyl-1,3-Thiazolidine-4-ones
A series of Schiff’s bases (E)-N-2-aryliden-2-(4-methyl-2-oxo-2H-chromen-7-yloxy)acetohydrazides 2a-l and N-(2-(substituted phenyl)-4-oxo-thiazolidin-3-yl)-2-(4-methyl-2-oxo-2H-chromen-7-yloxy)acetamides 3a-l were synthesized and evaluated for their ...
