experimental part, p. 3618 - 3628 (2011/02/16)
The published route to a series of 6'-arylamino substituted photochromic spirooxazines has been investigated with improvements made to perform the synthesis in satisfactory yield. The route has been exemplified with several novel derivatives prepared (including hydroxyl functionalised). Additionally, a one-pot procedure for the conversion of suitably functionalized 1,2-naphthoquinones into the photochromic compounds is reported. Copyright
