Novel selective [3 + 2] cycloaddition reactions between in situ formed nonstabilized azomethineylide generated from N-benzyl-1-methoxy-N-((trimethylsilyl)methyl)methanamine enabled by Lewis acids and bioactive molecules isothiazol-3(2H)-ones have been developed. The reaction selectively afforded novel thiazolidines or cyclo-fused oxazolidinones depending on Lewis acid catalyst system of reaction used

Provided is a heat-shielding material including a substrate; a metal particle-containing layer which contains flat metal particles with a hexagonal shape or a circular shape; and a low refractive index layer with a refractive index of 1.45 or less, in which flat metal particles in which a principle planar surface of the flat metal particles is set with a planar orientation in a range of 0° to ±30° on average with respect to the other surface of the metal particle-containing layer are 50% by number or more of all the flat metal particles, the low refractive index layer is arranged on an uppermost surface on an indoor side when installing the heat-shielding material on a window glass, and the heat-shielding performance, visible light transmittance, and lightfastness in the heat-shielding material are excellent; and a window glass.
