[polik25]

I want to prepared ascididemin by Moody's method (Tetrahedron 1992, 48, 3589-3602), but in the last fourth step I need Hanovia type photoreactor with quartz filter, which I have not. Please, can you advertised me, what can I do, or what other reaction conditions I must use to ensure the photolysis of quinoneimine.

Thanks a lot for advice.
