One-pot domino synthesis of polyvicinalamine monomers [PDF]

open access: yesCanadian Journal of Chemistry, 2011
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.

Fluorous‐Assisted One‐Pot Oligosaccharide Synthesis [PDF]

open access: yesEuropean Journal of Organic Chemistry, 2010
AbstractA new method for oligosaccharide assembly that combines the advantages of one‐pot synthesis and fluorous separation is described. After one‐pot glycosylations are completed, a fluorous tag is introduced into the reaction mixture to selectively “catch” the desired oligosaccharide, which is rapidly separated from non‐fluorous impurities by ...

The digital code driven autonomous synthesis of ibuprofen automated in a 3D-printer-based robot [PDF]

open access: yes, 2016
An automated synthesis robot was constructed by modifying an open source 3D printing platform. The resulting automated system was used to 3D print reaction vessels (reactionware) of differing internal volumes using polypropylene feedstock via a fused ...

A convenient tandem one-pot synthesis of donor-acceptor-type triphenylene 2,3-dicarboxylic esters from diarylacetylene [PDF]

open access: yes, 2014
A tandem one-pot method for the direct synthesis of polysubstituted triphenylene 2,3-dicarboxylic esters with different substitution patterns was developed by enyne metathesis of diarylacetylene, followed by Diels–Alder, aromatization and a cyclization ...
