Dendritic chiral phosphine lewis bases-catalyzed asymmetric aza-Morita-Baylis-Hillman reaction of N-sulfonated imines with activated olefins
Liu, Ying-Hao,Shi, Min
supporting information; experimental part, p. 122 - 128 (2009/04/10)
A series of polyether dendritic chiral phosphine Lewis bases was synthesized, and successfully applied to the asymmetric aza-Morita - Baylis - Hill -man reaction of N - sulfonated imines (N - arylmethyl -idene-4- methylbenzenesulfonamides) with methyl vin
Optical switching and antenna effect of dendrimers with an anthracene core
Cao, Derong,Dobis, Silvia,Gao, Chunmei,Hillmann, Sabine,Meier, Herbert
, p. 9317 - 9323 (2008/12/20)
Dendrimers 6Gi (i=1-4) consisting of an anthracene core and Frechet dendrons which are attached via a CH2OCH2 chain in the 9-position undergo quantitative and completely reversible intramolecular [4π+4π] cycloaddition. The
Photoisomerization of stilbene dendrimers: The need for a volume-conserving isomerization mechanism

, p. 596 - 605 (2007/10/03)
Highly branched stilbene dendrimers were synthesized and their photochemical behavior was studied. Even the stilbene dendrimer with molecular weight over 6500 underwent transcis isomerization in the excited singlet state within the lifetime of 10 ns. The
A comparison of two convergent routes for the preparation of metalloporphyrin-core dendrimers: Direct condensation vs. chemical modification
Pollak, Keith W.,Sanford, Elizabeth M.,Frechet, Jean M. J.
, p. 519 - 527 (2007/10/03)
Porphyrin-core dendrimers consisting of benzyl ether dendrons assembled around a porphyrin core have been prepared by two different convergent syntheses. The first involves the direct condensation of convergent dendrons having 3,5-disubstituted benzaldehy
Preparation of polymers with controlled molecular architecture. A new convergent approach to dendritic macromolecules
Hawker, Craig J.,Fréchet
, p. 7638 - 7647 (2007/10/02)
The novel convergent growth approach to topological macromolecules based on dendritic fragments is described. The polyether dendritic fragments are prepared by starting from what will become the periphery of the molecule and progressing inward. In the fir
