The synthesis and antifungalactivity of a novel series of 3-aryl-5-[(aryloxy)alkyl]-3-[(1H-imidazol-1-yl)-methyl]-2-methylisoxazolidines and related compounds, are discussed. The synthesis of the title compounds was accomplished via a 1,3-dipolar cycloaddition of α-substituted ketonitrones with l-alkenyl phenyl ethers (Scheme 2 and 3). The compounds were evaluated for in vitro antifungalactivity in
.alpha.-Substituted ketonitrone derivatives containing substitutents selected from hydrogen, phenyl, substituted phenyl, naphythyl, furan, thiopen, imidazolylmethyl and triazolylmethyl are useful as intermediates for the preparation of biologically active isoxazolidine compounds.

has been developed for the synthesis of aroyl-substituted imidazo-/benzimidazo-fused isoquinolines. The cascade reaction proceeds via a cross-aldol condensation of 2-(1H-imidazol-1-yl/benzimidazolyl-1-yl)-1-arylethanones and 2-bromobenzaldehyde followed by palladium-catalyzedintramolecular C–H functionalization. This approach offers a simple and efficient alternative one-pot protocol for the assembly
已开发出一种简单的方法来合成芳酰基取代的咪唑/苯并咪唑稠合的异喹啉。级联反应是通过2-(1 H-咪唑-1-基/苯并咪唑基-1-基)-1-芳酮和2-溴苯甲醛的交叉羟醛缩合进行的,然后进行钯催化的分子内C–H官能化。这种方法提供了一个简单而有效的一锅法方案,用于以中等到良好的产率组装咪唑/苯并咪唑并[2,1- a ]异喹啉。

Disclosed are compounds of formula (1.0) wherein R13 represents an imidazole ring; R14 represents a carbamate, urea, amide or sulfonamide group; R8 represents H when the alkyl chain between the amide group and the R13 imidazole group is substituted, or R8 represents a substituent such aa arylalkyl, heteroarylalkyl or cycloalkyl; and the remaining substituents are as defined herein. Also disclosed are compounds wherein R8 is H, and the alkyl chain between the amide group and the R13 imidazole group is unsubstituted. Also disclosed is a method of treating cancer and a method of inhibiting farnesyl protein transferase using the disclosed compounds.
