Chemistry is a science major with cience and engineering. The main research directions are chemical synthesis, new energy materials, nano-ceramics, nano-hybrid composite materials, preparation and modification of special coatings, In an article, 126456-43-7, name is (1S,2R)-1-Amino-2,3-dihydro-1H-inden-2-ol, introducing its new discovery. Application In Synthesis of (1S,2R)-1-Amino-2,3-dihydro-1H-inden-2-ol
Stereoselective synthesis of P-stereogenic aminophosphines: Ring opening of bulky oxazaphospholidines
A highly diastereoselective and efficient synthesis of P-stereogenic bulky alkyl and aryl aminophosphines that relies on ring opening of tert-butyl-oxazaphospholidine 2 is described. Ring opening with several organometallic reagents takes place with inversion of configuration at the phosphorus center as it has been demonstrated by X-ray analysis of two ring-opened intermediates. The unprecedented reactivity observed is attributed to the presence of a free NH functionality that facilitates the attack of the organometallic reagent in an SN2@P-type process.
The design and synthesis of related molecules that are more effective, more selective, and less toxic than aspirin are important objectives of biomedical research.Application In Synthesis of (1S,2R)-1-Amino-2,3-dihydro-1H-inden-2-ol, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 126456-43-7, in my other articles.
