<p>A series of new 3-substituted isoxazolecarboxamides have been prepared from aldehydes. The key step was a 1,3-dipolar cycloaddition reaction of nitrile oxides to a,b-unsaturated esters and amides. The cycloadditions to amides were mediated by chiral ligands and several products displayed excellent enantioselectivities. Some of the title compounds exhibited good fungicidal activities against <em>Alternaria alternata</em>, <em>Botrytis cinerea</em>, <em>Fusarium culmorum</em>, <em>Phytophthora cactorum</em>, and <em>Rhizoctonia solani</em> strains.</p>
