One-Pot Silver Nanoring Synthesis [PDF]
Silver colloidal nanorings have been synthesized by reducing silver ions with NaBH4 in trisodium citrate buffers. pH increase, by addition of NaOH, was used to speed up reduction reaction. The UV–vis absorption spectra of resulting silver nanorings

One-Pot Synthesis of Cycloparaphenylenes [PDF]
The preparation of cycloparaphenylenes ([n]CPPs) with their bent π-system poses a long-standing challenge in organic synthesis. In the current multi-step approaches to access CPPs, pre-angulated precursors were combined using transition metal-catalysed ...

Stereoselective one-pot synthesis of polypropionates [PDF]
Polypropionates are present in many natural products possessing high bioactivity and therapeutic value. Here the authors show a strategy for the stereoselective assembly of polypropionates with three or four stereocentres through a process that includes ...

One-pot domino synthesis of polyvicinalamine monomers [PDF]
Imidazole was generated in situ via a domino reaction between glyoxal, formaldehyde, and two units of aqueous ammonia. Aqueous bicarbonate and a carboxylic anhydride or dialkyl dicarbonate were added, yielding the corresponding N,N′-diacyl or N,N′-dicarbalkoxy-2-hydroxyimidazoline.

One-pot synthesis of spiroglycol
The synthesis of spiroglycol by one-pot reaction was studied using pentaerythritol, isobutyraldehyde and formaldehyde as starting materials. Under the optimum reacting conditions, the yield and purity of product were 93.6 % and 99.0 %, respectively ...

One‐Pot Synthesis of Thiocarbamates [PDF]
AbstractAn efficient isocyanide‐based synthesis of S‐thiocarbamates was discovered and thoroughly investigated. The new reaction protocol is a one‐pot procedure and allows the direct conversion of N‐formamides into thiocarbamates by initial dehydration with p‐toluene sulfonyl chloride to the respective isocyanide and subsequent addition of a sulfoxide ...

One-pot synthesis of (−)-Ambrox [PDF]
Abstract(−)-Ambrox is recognised as the prototype of all ambergris odorants. Widely used in perfumery, (−)-Ambrox is an important ingredient due to its unique scent and excellent fixative function. An environmentally friendly and practical preparation of (−)-Ambrox is still unavailable at present although a lot of attention has been paid to this hot ...

One-Pot Synthesis of Enantiopure Pyrrolopiperazines [PDF]
A simple one-pot protocol for the synthesis of fused pyrrolopiperazines with a complete diastereoselectivity has been developed. This novel methodology combined the Ugi reaction with a spontaneous enamine alkylation on a multicomponent domino reaction, starting from nonprotected diamines and arylglyoxals.

Electrochemical Synthesis of Imidazopyridine and Benzylidene Malononitrile
A one-pot electrochemical synthesis of two medically interesting compounds is presented. 2-Phenylimidazo[1,2-a]pyridine and 2-(4-fluorobenzylidene)malononitrile were prepared using previously used starting materials.
