Synthesis of N-vinyloxazolidinones and morpholines from amino alcohols and vinylsulfonium salts: Analysis of the outcome’s dependence on the N-protecting group by nanospray mass spectrometry

The effect of the nature of the N-protecting group on 1,2-amino alcohols in annulation reactions with diphenylvinylsulfonium triflate has been investigated. Although tosyl and sulfinamide groups give morpholines in high yields, the use of N-Cbz leads to a high-yielding synthesis of N-vinyloxazolidinones. The reactions were monitored by nanospray MS/MS, which revealed why reactions are successful and the fate of reactive intermediates in the unsuccessful reactions.

STEREODYNAMIC CHEMOSENSORS

The present invention relates to multifunctional chemosensors that can measure the concentration, enantiomeric excess (ee), and absolute configuration of chiral compounds. The chemosensors described herein may contain a backbone moiety that is bonded to a fluorescent moiety and a moiety for bonding a chiral compound. Backbone moieties may include aromatic groups, for example, naphthyl. The chemosensors described herein are useful for measuring concentration, enantiomeric excess, and absolute configuration of organic molecules in areas such as high throughput screening.

A stereodivergent synthesis of chiral 4,5-disubstituted bis(oxazolines)

Bis(oxazolines), disubstituted in the 4 and 5 positions, are synthesized from dimethylmalonyl bis-diamides of the suitable 1,2-disubstituted chiral aminoethanol. Starting from the same diamide, the ring closure can be realized either with retention (reflux in xylene with dibutyl tin dichloride – the Masamune protocol) or inversion (conversion into the mesylate and reflux with aqueous ethanolic NaOH) of the configuration at the chiral center in position 5.

Asymmetric Hydrogenation of Unfunctionalized Tetrasubstituted Acyclic Olefins

Asymmetric hydrogenation has evolved as one of the most powerful tools to construct stereocenters. However, the asymmetric hydrogenation of unfunctionalized tetrasubstituted acyclic olefins remains the pinnacle of asymmetric synthesis and an unsolved challenge. We report herein the discovery of an iridium catalyst for the first, generally applicable, highly enantio- and diastereoselective hydrogenation of such olefins and the mechanistic insights of the reaction. The power of this chemistry is demonstrated by the successful hydrogenation of a wide variety of electronically and sterically diverse olefins in excellent yield and high enantio- and diastereoselectivity.
