1-Trifluoromethylated isoquinolines via radical trifluoromethylation of isonitriles.
A simple and efficient approach to biologically important 1-trifluoromethylated isoquinolines starting with readily prepared β-aryl-α-isocyano-acrylates and the commercially available Togni reagent as the CF3 radical precursor is described. These transformations occur in the absence of any transition metals and the title compounds are obtained in moderate to excellent yields. This protocol comp...
متن کاملStereoelectronic effects on collagen stability: the dichotomy of 4-fluoroproline diastereomers.
Collagen is the most abundant protein in animals. Natural collagen consists of a triple helix of (Xaa-Yaa-Gly)n chains, in which the Xaa and Yaa residues are often l-proline. Here, a (2S,4S)-4-fluoroproline (flp) residue is shown to be greatly stabilizing in the Xaa position (but destabilizing in the Yaa position). In contrast, a (2S,4R)-4-fluoroproline (Flp) residue is shown to be greatly dest...
متن کاملAdditions to the knowledge of the genus Geastrum in Iran
Fungi belonging to the genus Geastrum are known as earth stars due to different layers with specific alignment in fruit-bodies. In this paper four species of the genus Geastrum viz. G. coronatum, G. rufescens, G. saccatum and G. schmidelii were reported as new for Iran. Previously reported specimen, G. corollinum (as G. recolligens)was newly collected and was studied in details. Newly reported ...
متن کاملDetecting Digital Chameleons 1 Detecting Digital Chameleons
Conversations are characterized by an interactional synchrony between verbal and nonverbal behaviors (Kendon, 1970). A subset of these contingent conversational behaviors is direct mimicry. During face to face interaction, people who mimic the verbal (Giles, Coupland, & Coupland, 1991) and nonverbal behaviors (Chartrand & Bargh, 1999) gain social advantage. Most research examining mimicry behav...
متن کاملthe significance of conjunction as a cohesive device in teaching writing
the research questions were as follows: 1. is there any relationship between the students concious awareness of the form and implications of the conjuncations and their improvement in using appropriate conjunctions? 2. does students knowledge of the from and the implications of the conjunctions help them to produce more coherent writings. 3. does a comparison between english conjunctions and th...
