The redox properties of the first member of a new family of bridgehead-modified difluoromethylenated homofullerenes, [6,6]-open C60(CF2)H2, were investigated by means of cyclic voltammetry and ESR spectroelectrochemistry.
After inspecting the front on December 27, Ridgway ordered the US I and IX Corps to organize a new defensive line around Koyang to Uijeongbu, called the Seoul Bridgehead line, to cover the Han River crossings in case the UN forces were forced to evacuate Seoul.
In continuation of our studies dealing with the utility of hydrazonoyl halides for synthesis of various bioactive bridgehead nitrogen polyheterocycles [21 30], we wish to report herein a new facile synthesis of new heterocycles containing thiazole and 1,3,4-thiadiazole or two thiazole rings in one molecular frame.
Based on peptide 1 and the analogue cyclo(3 5)[Sar1, Asp3, Lys5]-AII characterized by Matsoukas et al., we analyzed the agonistic and antagonistic activities, respectively, through a new monocyclic peptide series synthesized by using the following combinations of residues as bridgehead elements for the lactam bond formation: D- or L-Asp combined with D- or L-Lys or L-Glu combined with L-Orn.
A new podand bearing one carboxylate group at each terminal and a long linker from the bridgehead nitrogen has been designed and synthesized.
Such a Palestinian state, he says, would swiftly become, like Lebanon under Hizbullah and Gaza under Hamas, another bridgehead from which Iran and its proxies would pursue their ambition to extirpate the Jewish state.It may now take weeks for Israel to choose a new government.
(It helps that VR fiction like Ready Player One — a copy of which is issued to every Oculus Rift employee — has already built a bit of a bridgehead there).
The Canadian attack on San Leonardo by the Seaforth Highlanders of Canada began late on 5 December 1943 with A Company establishing a bridgehead across the Moro, taking heavy casualties.
Despite the K1 success of Ray Sefo and Mark Hunt, it would take the best part of 20 more years before the sport held a decent bridgehead in New Zealand.
