Programmable One-Pot Synthesis of Oligosaccharides

Biochemistry, 2019
Carbohydrates make up one of the four major classes of biomolecules, often conjugated with proteins as glycoproteins or with lipids as glycolipids, and participate in many important biochemical functions in living species. However, glycoproteins or glycolipids often exist as mixtures, and as a consequence, it is difficult to isolate individual ...

A Simple One-Pot Synthesis of Methyltribromosilane

Phosphorus, Sulfur, and Silicon and the Related Elements, 2007
A simple one-pot synthesis of methyltribromosilane has been developed. The straightforward reaction of a slight excess of silicon tetrabromide with one equivalent of powdered methyllithium in refluxing pentane produces methyltribromosilane in high yields.

A New One-Pot Synthesis of Alkynylphosphonates

Organic Letters, 2000
A method for the palladium-catalyzed synthesis of alkynylphosphonates from 1,1-dibromo-1-alkenes has been developed. In general, the best catalyst system for this transformation was found to be Pd(OAc)(2), dppf, H-phosphonate, propylene oxide, DMF, 80 degrees C.

Stereoselective One-Pot Synthesis of Oxazolines

The Journal of Organic Chemistry, 2008
Treatment of alkenes with NBS, a nitrile, NaHCO3 and water in the presence of Cu(OTf)2 or Zn(OTf)2 is reported to furnish oxazolines in one pot and good yields. The reaction is equally applicable to chalcones.

One Pot Synthesis of Aryldiazepinothiophenones

Synthetic Communications, 2003
Aryldiazepinothiophenones 2 were prepared from the reaction of o-phenylenediamines with acetone in the presence of 2-mercaptopropionic acid. Fused thiazolobenzodiazepines 3 along with fused thiazolobenzimidazoles 4 and 1,5-benzodiazepines 5 were obtained as by-products.

A “One-Pot” Synthesis of Blattellaquinone

The Chemical Educator, 2014
An experimental protocol is described that allows preparation of blattellaquinone in higher yield and purity than those obtained by a procedure previously published. A variation on this protocol allows the target molecule to be prepared in a single lab session.

One-pot synthesis of sulfonyl benzotropones

Organic & Biomolecular Chemistry
This paper describes SeO2-mediated one-pot tandem cyclocondensation of 1,3-bis-sulfonylacetones and o-dimethylarenes via (4 + 3) annulation to construct diverse bis-sulfonyl benzotropones.

One‐Pot Synthesis of Spiropyrans

Asian Journal of Organic Chemistry, 2019
AbstractA highly efficient one‐pot synthetic strategy for the preparation of spiropyrans was developed. The method is free of special equipment and operations, and meanwhile, it is energy‐ and time‐saving compared to the reported three‐step procedures.
