Anionic synthesis of primary amine functionalized polystyrenes via hydrosilation of allylamines with silyl hydride functionalized polystyrenes
Quirk, Roderic P.,Kim, Hoon,Polce, Michael J.,Wesdemiotis, Chrys
, p. 7895 - 7906 (2005)
A general anionic ω-chain-end functionalization methodology is described and illustrated by the synthesis of ω-primary amine functionalized polystyrenes. First, the quantitative ω-silyl hydride functionalization of well-defined poly(styryl)lithium (Mn = 2200 and 14 100 g/mol) was effected with dimethylchlorosilane in hydrocarbon solution at room temperature. In the second step, involving amination by hydrosilation, the silyl hydride functionalized polystyrene was added quantitatively to 3-[N,N-bis(trimethylsilylamino]-1-propene, a protected amine, using Karstedt's Pt(0) hydrosilation catalyst in benzene. One of the principal advantages of this method is the fact that it is not necessary to use protecting groups for many functional groups, as illustrated by the quantitative primary amine functionalization of ω-silyl hydride functionalized poly(styryl)lithium with allylamine using the Karstedt's hydrosilation catalyst. The silyl hydride and amine functionalized polystyrenes were characterized by SEC, FTIR, 1H and 13C NMR, MALDI-TOF mass spectrometry, and end-group titration.

The first protocol for the synthesis of unsymmetrical bifunctional 1,1,3,3-tetramethyldisiloxane derivatives via subsequent hydrosilylation of alkenes and alkynes is presented. The methodology described has vast functional group tolerance and is extremely efficient towards the formation of novel disiloxane-based building blocks.

In search of myosin II inhibitors with superior research tool properties, a chemical optimization campaign of the blebbistatin scaffold was conducted in this paper. (S)-Blebbistatin is the best known small-molecule inhibitor of myosin II ATPase activity. Unfortunately, as a research tool this compound has several deficiencies: it is photolabile and (photo)toxic, has low water solubility, and its (fluorescent) precipitates interfere in (fluorescence) readouts. In view of obtaining tool compounds with improved properties, both enantiomers of a series of D-ring modified polar analogs were prepared. We identified (S)-3′-hydroxyblebbistatin (S)-2 and (S)-3′-aminoblebbistatin (S)-3 as two myosin II inhibitors with a 30-fold higher water solubility than (S)-blebbistatin. These molecules furthermore do not cause interference in (fluorescence) readouts. (S)-2 and (S)-3 thus are superior alternatives to (S)-blebbistatin as research tools to study myosin II.

A synthesis of 1-aminophosphonate derivative of methylsiloxane oligomer was developed. A methodology of the introduction of 1-aminophosphonate fragment not only into the stable siloxane structures, but also into hydrolytically unstable alkoxyfunctional organosilicon compounds was suggested.
Reaction of hexylsilane with N-substituted allylamine and allyl chloride

, p. 541 - 544 (2008/02/07)
Reactions of allyldiethylamine and allylbis(trimethylsiyl)amine with hexylsilane are studied. The former reaction involves hydrogen evolution and Si-Si bond formation. The contribution of hydrosilylation is insignificant. Substituent exchange between the nitrogen and silicon atoms in the silane is found. In the reaction with allylbis(trimethylsilyl)amine, no evolution of hydrogen is observed, and hydrosilylation takes place. With allyl chloride, hydrosylilation, reduction, and Si-Si bond formation are observed. Quantumchemical calculations for the reactions with diethylallylamine and allylbis(trimethylsilyl)amine were carried out at the PM3, B3LYP/6-31G**, and B3LYP/LanL2DZ levels to show that these reactions all are thermodynamically allowed, and the difference in the behavior of the amines is explained by kinetic and conformational factors.
