    摘要: Novel glycolipid derivatives wherein the substituent of the sphingosine base moiety is alkyl having a shorter carbon chain, substituted or unsubstituted cycloalkyl, substituted or unsubstituted aryl, or substituted or unsubstituted aralkyl; an efficient process for mass-producing the same economically; and intermediates useful in the production thereof. Specifically, glycolipid derivatives represented by the general formula (I) are chemically synthesized: (I) wherein R is substituted or unsubstituted linear alkyl having 1 to 7 carbon atoms, substituted or unsubstituted cycloalkyl, substituted or unsubstituted aryl, or substituted or unsubstituted aralkyl; and R is substituted or unsubstituted alkyl having 1 to 35 carbon atoms, substituted or unsubstituted aryl, or substituted or unsubstituted aralkyl.

    摘要: The present invention is directed to a method of converting an aryl compound to an aniline compound, comprising the steps of (1)providing an aryl compound containing a halide group or a sulfur-containing group; (2) reacting the aryl compound with an a reactant having the structure wherein R 1 ,R 2 , and R 3 are each independently selected from the group consisting substituted or unsubstituted alkyl, substituted or unsubstituted heteroalkyl, substituted or unsubstituted aryl, substituted or unsubstituted heteroaryl, substituted or unsubstituted arylalkyl,substituted or unsubstituted heteroarylakyl, and combinations thereof; R 4 is selected from the group consisting hydrogen, substituted or unsubstituted alkyl, substituted or unsubstituted alkenyl, substituted or unsubstituted alkynyl, substituted or unsubstituted heteroalkyl, substituted or unsubstituted aryl, substituted or unsubstituted heteroaryl,substituted or unsubstituted arylalkyl, substituted or unsubstituted heteroarylalkyl, and SiR 1 R 2 R 3 ; and A is H or an alkali metal; the reacting step taking place in the presence of a Group 8 transition metal catalyst under reaction conditions that form an aryl silylamine intermediate, with the proviso that when A is H in the reactant, the reacting step further comprises a base; and (3) converting the aryl silylamine intermediate to the aniline compound.
