Naphtha pyrans

Structural studies of 2-amino-4H-naphtho[2,l-fc]pyrans (87JOU369, 02RCB2238) and enantiomerically pure naphtha[l,2-b]pyrans (96JHC27) revealed a similarity in structural properties to those of 8 and 9. 

The reaction was studied on nonannulated aminopyrans (89M1101), tetrahydrochromenes, naphtha[2,l-b]pyrans (04MI2), pyrano[3,2-/j]quino-lines (91BCJ668), pyrano[3,2-c]coumarines (01MOL519, 03MOL275), and...
