Total synthesis of kaempferol and methylated kaempferol derivatives
Lee, Yean-Jang,Wu, Tsao-Dong
, p. 201 - 206 (2001)
Kaempferol (1), a natural product from various plants, was synthesized in which the longest linear sequence is only seven steps in overall yields of 47% from commercially available 1,3,5-trimethoxybenzene (10). The methylated kaempferols 2-5 were also prepared by use of this concise synthetic methodology. The key transformations in this synthesis involved the I2 oxidative-promoting-cyclization and DDO oxidative hydroxylation. Several strategies to achieve 1 are provided.

Flavonol glycosides from Cassia hirsuta
Rao,Damu,Jayaprakasam,Gunasekar
, p. 305 - 306 (1999)
A new flavonol glycoside, kaempferol 3-O-α-L-rhamnopyranosyl (1→2)- α-L-rhamnopyranoside (1), was isolated from the flowers of Cassia hirsuta along with two known flavonol glycosides, kaempferol 3-O-rutinoside and rutin. The structure of compound 1 has been established on the basis of spectral data and by acid hydrolysis.
