The present disclosure relates to compositions and methods for the treatment of diseases or disorders (e.g., cancer) with bi-steric inhibitors of mTOR in combination with RAS inhibitors. Specifically, in some embodiments this disclosure includes compositions and methods for inducing apoptosis of tumor cells and/or for delaying, preventing, or treating acquired resistance to RAS inhibitors using bi-steric mTOR inhibitors.
The disclosure features macrocyclic compounds, and pharmaceutical compositions and protein complexes thereof, capable of inhibiting Ras proteins, and their uses in the treatment of cancers.
Asymmetric Synthesis of 1,2-Amino Alcohols Using<i>tert</i>-Butanesulfinimines as Chiral Auxiliary
作者:Yong Hae Kim、Chang Hong Ko、Doo Young Jung、Min Kyun Kim
DOI:10.1055/s-2004-836070
日期:——
Facile and highly stereoselective synthesis of 1,2-aminoalcohols has been achieved by the addition of [(dimethylphenyl-silyl)methyl] magnesium chloride to the tert-butanesulfinimines, followed by Fleming-Tamao oxidation of the silicon moiety.
Highly Diastereoselective Synthesis of <i>N</i>-<i>tert</i>-Butylsulfinylpropargylamines through Direct Addition of Alkynes to <i>N</i>-<i>tert</i>-Butanesulfinimines

The addition of benzyltrimethylsilane 2 to imines 1 triggered by TBAF in the presence of 4A molecular sieves gave rise to the corresponding alpha-benzylated amines 3 in good yields. Moderate to high diastereoselectivity was obtained in the reactions of tert-butanesulfinyl imines with 2. (c) 2006 Elsevier Ltd. All rights reserved.
