Tautomerization of adenine facilitated by water: computational study of microsolvation.
We present calculations for the mechanism and the barrier heights of tautomerization of adenine. We find various pathways for the 9(H) <--> 7(H) and 9(H) <--> 3(H) tautomerization. One mechanism for the 9(H) --> 7(H) tautomerization involves an sp(3)- or carbene-type intermediate, whereas the other proceeds via imine intermediates. Tautomerization from the 9(H) tautomer to 7(H) or 3(H) is predi...
متن کاملMulticomponent reactions are accelerated in water.
Two multicomponent reactions, the Ugi and Passerini reactions, are accelerated by the use of aqueous solutions. The rate enhancements compared to those by organic solvents can approach 300-fold. Reactions performed in water offer another advantage that products are often insoluble, permitting direct isolation by precipitation. The methods were applied to the preparation of three small combinato...
متن کاملKnots Are Determined by Their Complements
The notion of equivalence of knots can be strengthened by saying that K and K' are isotopic if the above homeomorphism h is isotopic to the identity, or equivalently, orientation-preserving. The analog of Theorem 1 holds in this setting too: if two knots have complements which are homeomorphic by an orientation-preserving homeomorphism, then they are isotopic. Theorem 1 and its orientation-pres...
متن کاملMicrosolvation of F.
A staggering structural diversity for the microsolvation of F- with up to six water molecules is uncovered in this work. Given the structural variety and the proximity in energy among several local minima, we show here that in order to match available experimental data, statistical averages over contributing structures are needed, rather than assigning experimental values to isolated structures...
متن کاملKnots Are Determined by Their Complements
This answers a question apparently first raised by Tietze [T, p. 83]. It was previously known that there were at most two knots with a given complement [CGLS, Corollary 3]. The notion of equivalence of knots can be strengthened by saying that K and K' are isotopic if the above homeomorphism h is isotopic to the identity, or, equivalently, orientation-preserving. The analog of Theorem I holds in...
