Functional analysis of an aspartate-based epoxidation catalyst with amide-to-alkene peptidomimetic catalyst analogues
Jakobsche, Charles E.,Peris, Gorka,Miller, Scott J.
supporting information; experimental part, p. 6707 - 6711 (2009/03/12)
Subtle exchange: Replacement of an amide function with alkene or fluoroalkene groups provides a new class of epoxidation catalysts (see scheme). The structure-dependent catalytic behavior of these isosteric peptides provides mechanistic insights in their mode of action. (Chemical Equation Presented).
Deprotection of a silyl group with mesoporous silica
Itoh, Akichika,Kodama, Tomohiro,Masaki, Yukio
, p. 861 - 864 (2008/02/11)
The triethylsilyl (TES) group of silyl ethers of several types is selectively and easily removed in the presence of a t-butyldimethylsilyl (TBDMS) group with a mesoporous silica MCM-41/MeOH heterogeneous system. Comparison of the efficiency was carried out among several solvents, and among such promoters as common zeolites and ion-exchange resins. Furthermore, FSM-16, another mesoporous silica, was examined for the possibility of recycling by re-calcination at 400°C after the reaction.
A remarkable solvent effect toward the Pd/C-catalyzed cleavage of silyl ethers
Sajiki, Hironao,Ikawa, Takashi,Hattori, Kazuyuki,Hirota, Kosaku
, p. 654 - 655 (2007/10/03)
Selective hydrogenation conditions of olefin, benzyl ether and acetylene functionalities in the presence of TBDMS or TES ether have been developed.
Selective deprotection of triethylsilyl group in the presence of t-butyldimethylsilyl group with MCM-41/MeOH heterogeneous system
Itoh, Akichika,Kodama, Tomohiro,Masaki, Yukio
, p. 357 - 359 (2007/10/03)
Triethylsilyl (TES) group of silyl ethers of several types is selectively and easily removed in the presence of t-butyldimethylsilyl group (TBS) with a mesoporous silica MCM-41/MeOH heterogeneous system. Comparison of the efficiency was carried out among several solvents, and among such promoters as common zeolites and ion-exchange resins. Thieme Stuttgart.
Selective acceleration for deprotection of benzyl ethers with ti-HMS
Itoh, Akichika,Kodama, Tomohiro,Maeda, Shiro,Masaki, Yukio
, p. 9461 - 9464 (2007/10/03)
Ti-HMS, a Ti-loaded hexagonal mesoporous silica, was found to accelerate deprotection of benzyl ethers under hydrogenolytic conditions with palladium catalyst. Such acid-sensitive functional groups as silyl ether and acetal moieties in the molecule were little affected by Ti-HMS, which possesses Lewis acid sites due to Ti-atom.
