Group 12 synthesis

With the aim of studying the formation of the 2.5-helix in water as well as to introduce side chain diversity, Gellman and his group synthesized / -peptides from a variety of / -amino acid building blocks (34-39) constrained with five-membered rings (Fig. 2.21). [Pg.70]

The susceptibility of cyclodisilazanes to nucleophilic attack by aromatic amines has also been used to prepare silazane containing polymers. Polysilazane cyclo-linear chains with aromatic spacing groups, synthesized by polycondensations of difunctional cyclodisilazanes with bis-phenols and N.N -diorganosilane diamines, have been reported (13). [Pg.175]

In a more recent approach, the same group synthesized macrocycles using a Passerini reaction followed by a ring-closing metathesis [23], but the final cycliza-tion gave only low yields. [Pg.545]

The Conia group synthesized [4]rotane 78 from a dispiro[2.0.2.2]oct-7-ene derivative. This and nearly all other syntheses of rotanes include one or more steps of carbene additon to an exocyclic double bond 24). [Pg.17]

In a related and more recent study by the same group, syntheses of various solid-supported acylating agents for microwave-mediated transformations of amines, alcohols, phenols, and thiophenols have been presented [129]. In a microwave-mediated... [Pg.370]

In contrast to 3- and (4-pyridyl)boranes, 2-pyridylborane is considered an unsuitable Suzuki coupling partner because it forms an unusually stable cyclic dimer resembling a dihydroanthracene. This obstacle can be circumvented by using 2-pyridylboronic ester in place of 2-pyridylborane. For example, Diederich s group synthesized 2-(2-pyridyl)-8-methylquinoline (49) via the Suzuki coupling of 2-pyridylboronic ester 47 and 2-bromo-8-methylquinoline (48) [36]. [Pg.192]

Grigg s group synthesized a unique bicyclic P-lactam 108 via an intramolecular Heck reaction from 107 [87, 88]. The 7-membered ring was formed via an unusual insertion at C(3) of furan, an aromatic rc-system. [Pg.286]

Recently, Jen s group synthesized a series of high Tg fluorinated polymers with a hole transporting TPA group covalently attached as side chains (55) (Scheme 3.21) [99]. This type of polymer can be processed into thin films by simple thermal cyclopolymerization without introducing any by-products [100]. The polymers (56, 57) are insoluble in most organic solvents and can be conveniently streamlined into a multilayer device fabrication process [101,102]. The... [Pg.318]

A new PET-based chemosensor for uronic and sialic acids utilizing the cooperative action of boronic acid and metal chelate was reported by Shinkai and co-workers. This group synthesized a novel fluorescent chemosensor molecule bearing both an o-aminomethylphenylboronic acid group for diol binding to a saccharide and a l,10-phenanthroline-Zn(II)chelate moiety for the carboxylate binding, which enables this sensor to discriminate between neutral monosaccharides and acidic compounds [110],... [Pg.221]

Recent efforts to synthesize triiodinated benzene derivatives that are taken up by the liver have been published by Ranganathan [76]. This group synthesized lipophilic and/or amphiphilic derivatives of the angiography contrast agent, diatrizoate (Fig. 10). [Pg.189]

The same research group synthesized also 2//-azirine-2-phosphine oxides 543 in a similar manner (equation 242). [Pg.480]

The Takemoto group synthesized a series ofdiaminocyclohexane-based thiourea derivatives (e.g., 12, 40, 57, and 58) for catalysis of the Michael addition [149-152] ofmalonates to trons-j3-nitrostyrenes (Figure 6.18) [129, 207]. In the model, Michael addition of diethyl malonate to trons-]3-nitrostyrene at room temperature and in toluene as the solvent tertiary amine-functionalized thiourea 12 (10mol% loading) was identified to be the most efficient catalyst in terms of catalytic activity (86%... [Pg.203]
