Sheet 4, (2017/08/01)
This disclosure relates to synthetic coupling methods using catalytic molecules. In certain embodiments, the catalytic molecules comprise heterocyclic thiolamide, S-acylthiosalicylamide, disulfide, selenium containing heterocycle, diselenide compound, ditelluride compound or tellurium containing heterocycle. Catalytic molecules disclosed herein are useful as catalysts in the transformation of hydroxy group containing compounds to amides, esters, ketones, and other carbon to heteroatom or carbon to carbon transformations.
In situ carboxyl activation using a silatropic switch: A new approach to amide and peptide constructions
Wu, Wenting,Zhang, Zhihui,Liebeskind, Lanny S.
, p. 14256 - 14259 (2011/11/05)
The novel reactivity of O-silylthionoesters with amine nucleophiles to generate oxoamides (rather than thioamides) is described. A straightforward first-generation trimethylsilylation protocol using bistrimethylsilylacetamide (BSA) combined with the unique reactivity of the O-silylthionoesters toward 1° and 2° amines to generate oxoamides provides the simplest means of activating a thiol acid for peptide bond formation at neutral pH. Excellent stereoretention is observed.
A fast procedure for the preparation of amides/peptides from carboxylic acids and azides via two redox reactions: Application to the synthesis of methionine enkephalin
Ghosh, Sunil K.,Verma, Rekha,Ghosh, Usha,Mamdapur, Vasant R.
, p. 1705 - 1711 (2007/10/03)
A one-pot self regulated approach for the synthesis of amides/peptides based on two reduction-oxidation (redox) reactions has been described. The primary and secondary amides/peptides are made by using azidotrimethylsilane and alkyl azides/α-azido acid de
