We synthesize optically active (R)-terbutaline 2, which is an anti-asthmatic drug, through recyclable catalytic asymmetric transfer hydrogenation (RCATH). Various chloroketones 4 were prepared and RCATH was performed on them. The products exhibit moderate

experimental part, p. 6318 - 6325 (2012/06/18)
A single component epoxy system in which the resin and hardener components found in many two-component epoxies are combined onto the same molecule is described. The single molecule precursor to the epoxy resin contains both multiple epoxide moieties and a

Page/Page column 7-10, (2009/05/29)
A dendron (2) comprising a focal point (4) and a plurality of fluorinated end groups (9) is disclosed, including one having a thiol, a silane, a carboxylic acid, a phosphonate or another moiety at the focal point suitable for chemisorption to a substrate

(Chemical Equation Presented) The rational design, synthesis, and characterization of a series of novel perfluorinated dendrons 14a,b, 25a,b, 26a,b, and 18 are described. The dendrimers were designed to have a thiol at the focal point for attachment to a gold surface to enable the fabrication of self-assembled monolayers (SAMs). Perfluorinated tails were attached to the periphery to provide solubility in supercritical carbon dioxide, and to increase the hydrophobicity and the stability of self-assembled monolayers formed. Mitsunobu reactions were utilized to provide high-yielding steps allowing large-scale production of the novel dendrimers.
Incorporation of functional guest molecules into an internally functionalizable dendrimer through olefin metathesis
Liang, Catherine O.,Frechet, Jean M. J.
, p. 6276 - 6284 (2008/02/02)
A poly(aryl ether) dendrimer bearing 22 allyl groups throughout the interior of the molecule has been prepared using a convergent synthetic approach. The internal functionalities of this dendrimer can be used to attach small molecule guests to the interio

This manuscript reports the synthesis and the self-assembly of (4-3,4,5-3,5)nG2-CH2-Boc-L-Tyr-L-Ala-OMe dendritic dipeptides (n = 12, 16). These dendritic dipeptides self-assemble both in solution and in solid states into helical por
Cross-linking dendrimers with allyl ether end-groups using the ring-closing metathesis reaction
Elmer, Stephanie L.,Zimmerman, Steven C.
, p. 7363 - 7366 (2007/10/03)
A third generation Frechet-type dendrimer containing 24 allyl ether end-groups was synthesized, cross-linked using the ring-closing metathesis (RCM) reaction, and the core was removed hydrolytically without significant fragmentation. The results are analo
Rapid synthesis of dendrimers based on calix[4]resorcinarenes

, p. 4135 - 4139 (2007/10/03)
Calix[4]resorcinarenes are phenolic macrocyclic compounds, and readily available from resorcinols and aldehydes. We were interested in calix[4]resorcinarenes as highly functionalized core molecules for the rapid synthesis of dendrimers because of their ea
Induction of liquid crystallinity by host-guest interactions
Van Nunen, Johanna L. M.,Folmer, Brigitte F. B.,Nolte, Roeland J. M.
, p. 283 - 291 (2007/10/03)
A molecular clip is described which binds aromatic guests by an induced fit mechanism. It contains twelve long aliphatic chains and can evoke liquid-crystalline properties in a variety of molecules, including polymers and porphyrins, by a process of molecular recognition.
