Divergent syntheses of indolizines and 2,4-disubstituted pyrroles by the silver-catalyzed cyclization of 2-pyridyl alkynyl carbinols with isocyanides are reported. These methods provide an effective route to highly functionalized indolizines and 2,4-disubstituted pyrroles in good to excellent yields. The 2,4-disubstituted pyrroles are synthesized by an(More)
Salinity is an adverse environmental stress that limits the yield and quality of maize. As one of the most important osmolytes present in higher plants, glycinebetaine helps stabilize metabolism in plant cells and protects the constituents of cells from damage. In this study, a gene from Atriplex micrantha that encodes betaine aldehyde dehydrogenase was(More)
To study the influence of coarse particle addition on solids distribution of circulating fluidized bed (CFB), some experiments has been done on a 0.25m¡Á0.25m¡Á6.07m square circulating fluidized bed in this paper. The axial pressure drop, local solids holdup and coarse particle fraction in the CFB system was measured and analyzed.(More)
