8β-Ethoxyeremophil-3,7(11)-diene-8α,12;6α,15-diolide
The title compound, C17H20O5, an eremophilane sesquiternoid, was isolated from the roots of Ligularia lapathifolia. The mol-ecule contains four fused rings of which the six-membered ring A adopts a half-chair conformation, the six-membered ring B adopts a chair conformation, the five-membered ring C is almost planar (r.m.s. deviation = 0.015 Å) and the five-membered ring D adopts an envelope co...

متن کاملGas-Phase Synthesis of 1-Silacyclopenta-2,4-diene.
Silole (1-silacyclopenta-2,4-diene) was synthesized for the first time by the bimolecular reaction of the simplest silicon-bearing radical, silylidyne (SiH), with 1,3-butadiene (C4 H6 ) in the gas phase under single-collision conditions. The absence of consecutive collisions of the primary reaction product prevents successive reactions of the silole by Diels-Alder dimerization, thus enabling th...

The limited description, discovery and integration mechanisms of current web service-based systems have many setbacks that hinder the extension and incorporation of dynamic capabilities into these systems. In this paper we present a novel software architecture called intelligent aspect-oriented web services (IAOWS) which addresses these problems and further improves on this technology by allowi...
متن کاملLecture 15 — April 12 , 2012
We care not only about the value of the minimum element, but also about the index k of the minimum element between A[i] and A[j]; given the index, it is easy to look up the actual value of the minimum element, so it is a more interesting problem to find the index of the minimum element between A[i] and A[j]. The range minimum query problem is not a tree problem, but it closely related to a tree...
