그리세오풀빈과 히드록실아민, 히드라진, 세미카바지드, 2, 4-디니트로페닐히드라진, 에틸아민 및 페닐히드라진과 같은 아미노화합물과의 반응에서 4'-옥심, 4'-히드라존, 4'-세미카바존, 4'-(2, 4-디니트로페닐히드라존), 2'-에틸아미노그리세오풀빈 유도체, 2'-페닐히드라존과 같은 화합물을 얻었으며, 적용된 아미노화합물은 그리세오풀빈 B 고리의 케톤기를 전혀 선호하지 않았으며, C고리의 β-위치와 4'-카르보닐기를 선호했다. 그중 에틸아민은 β-위치를 선호했고, 페닐히드라진과 히드라진은 β-위치와 4'-위치에서 반응이 일어났으나 페닐히드라진은 β-위치를 우선적으로 선호했다. Reactions of griseofulvin with hydroxylamine, ethylamine, phenylhydrazine, semicarbazide, and 2, 4-dinitrophenylhydrazine gave 4'-oxime, 2'-phenylhydrazone, 4'-semicarbazone, 4'-(2, 4-dinitrophenylhydrazine), and 2'-ethylamino griseofulvin derivative. Reactions of these amino compounds did not occur to carbonyl group on the ring B of griseofulvin but to 2'-carbon or 4'-carbonyl group on the ring C. Ethylamine has selectively reacted to 2'-carbon and phenyhydrazine has reacted predominantly to 4'-carbon.

We present a novel process to fabricate three-dimensional (3D) metallic patterns from 3D printed polymeric structures utilizing different hygroscopic swelling behavior of two different polymeric materials. 3D patterns are printed with two different polymers as cube shape. The surface of the 3D printed polymeric structures is plated with nickel by an electroless plating method. The nickel patterns on the surface of the 3D printed cube shape structure are formed by removing sacrificial layers using the difference in the rate of hygroscopic swelling between two printing polymer materials. The hygroscopic behavior on the interfaced structure was modeled with COMSOL Multiphysics. The surface and electrical properties of the fabricated three-dimensional patterns were analyzed and characterized.
