These dendritic NOBIN derived Schiff base ligands have been applied to titanium catalyzed hetero-Diels-Alder reaction of Danishefshy's diene and aldehydes, affording the corresponding 2-substituted 2, 3-dihydro-4H-pyran-4-one in quantitative yields and excellent enantioselectivities (up to 97. 2%ee). Comparing the reactivities and enantioselectivities of reaction catalyzed by the titanium complexes of these Schiff base ligands, it was found that a series of ligands L〓 were superior to the other three series of ligands L〓, L〓 and L〓, a significant positive NLE and a dendrimer effect existed in the L〓 dendritic catalyst system. The disposition of the dendritic wedges and the dendron size in the ligands were observed to have a significant impact on the enantioselectivity of the reaction.

Language acts as not only a tool of thinking for human beings but also influences and restricts human beings" thought. The Sapir-Whorf Hypothesis originated in German linguistics tradition. In the eighteenth century, German scholar Herder once put forth that language was the tool, the content and the style of man"s thought. German linguist Humboldt further asserted that language was the formation organ of "thought", every language consisted of a peculiar view on the world. Boas created American descriptive linguistics by emphasizing on the description of language structure.
