Hauser, Frank M.,Baghdanov, Vaceli M.
, p. 4676 - 4681 (2007/10/02)
A new, general route to benzopyran-1-ones 33 from phthalaldehydic acids 27 and nitroalkanes 28 is described.The sequence permits strightforward variation of both the 3-substituent and the pattern of functionalization on the aromatic ring of the benzopyran
