title: An organic photochromic compound: (2S)-2'-ethoxy-1,3,3-trimethyl-6'-(piperidin-1-yl)spiro[indoline-2,3'-3'H-naphtho[2,1-b][1,4]oxazine].
abstract: In the course of our synthesis of hybrid photochromic compounds, the unexpected new organic photochromic title compound, C(29)H(33)N(3)O(2), (I), was obtained. It is a derivative of the parent spirooxazine 1,3,3-trimethyl-6'-(piperidin-1-yl)spiro[indoline-2,3'-3'H-naphtho[2,1-b][1,4]oxazine], (II). The 2'-ethoxy group gives (I) different photochromic properties from its parent spirooxazine (II).
