Double chirality transmission in trityl amines: Sensing molecular dynamic stereochemistry by circular dichroism and DFT calculations
Sciebura, Jacek,Gawronski, Jacek
experimental part, p. 13138 - 13141 (2012/02/02)
Con-figured out: The tert-butyl group can be formally seen as "less" sterically demanding (M) than the methyl group (L). This is the case when a CD-active trityl group at the nitrogen atom is used to report the chirality of the carbon substituent with two
Reaction of N-trityl amino acids with BOP: Efficient synthesis of t-butyl esters as well as N-trityl serine- and threonine-β-lactones
Sliedregt, Karen M.,Schouten, Arie,Kroon, Jan,Liskamp, Rob M.J.
, p. 4237 - 4240 (2007/10/03)
Upon exposure to methoxymethylamine and BOP, the stable hydroxybenzotriazolyl amide of TrPheOH was isolated instead of the expected Weinreb amide. This amide behaves as an active amide similar to the Weinreb amide and could be used, among others, for the
Synthesis of alkene dipeptide isosteres employing the Wittig-Still rearrangement
Bol,Liskamp
, p. 6425 - 6438 (2007/10/02)
A new approach to the synthesis of alkene dipeptide isosteres is reported which features the use of the [2,3]-Wittig-Still rearrangement, carried out in hexanes. Employing this rearrangement alkene dipeptide isosteres of 'Gly-Xxx' are accessible starting
