synthesis of optically pure vic sulfanyl amines mediated by a remote sulfinyl group
ChemInform, 2012Co-Authors: Yolanda Arroyo, Inés Alonso, Ascension M Sanztejedor, Jose L GarciaruanoAbstract:Treatment of the sulfoxide (I) with N-phenyl and N-methoxyphenyl aldimines allows highly stereoselective access to syn-sulfanyl amines.
-
synthesis of optically pure vic sulfanyl amines mediated by a remote sulfinyl group
Organic Letters, 2011Co-Authors: Yolanda Arroyo, Inés Alonso, Ascension M Sanztejedor, Jose L GarciaruanoAbstract:Enantiomerically pure syn-1,2-diaryl-1,2-sulfanylamine derivatives can be obtained in a completely stereoselective manner by reaction of the benzylcarbanion Li-(S)-1 with N-phenyl (or PMP)-arylidene aldimines and further desulfinylation with t-BuLi. Theoretical studies at the DFT (mPW1PW91) level with the CPCM model, by using the Gaussian09 program, provide a good explanation for the stereochemical results.

highly diastereoselective katsuki jacobsen oxidation epoxidation of α silyloxy sulfinyl dienes synthetic applications
Journal of Organic Chemistry, 2009Co-Authors: Roberto Fernandez De La Pradilla, Alejandro Castellanos, Inaki Osante, Ignacio Colomer, Mateo I SanchezAbstract:Katsuki−Jacobsen oxidation−epoxidation of acyclic α-silyloxy sulfinyl dienes, followed by acid-promoted cyclization, leads to 2,5-trans-Sulfonyl dihydrofurans with good selectivities. As an application, the formal syntheses of (6S,7S,9R,10R)- and (6S,7S,9S,10S)-6,9-epoxynonadec-18-ene-7,10-diols is reported.
