Substituierte Methylphosphonate als Synthone fuer alicyclische α-funktionalisierte Phosphonate

Neidlein, Richard,Eichinger, Thomas

, p. 1037 - 1044 (1992)

Syntheses of cycloalkylphosphonates 4, and 6-8 are described, starting from the substituted methylphosphonates 1-3.Hydrolysis of the phosphonic esters 4 and 8 yield the free phosphonic acids 5 and 10; the partial hydrolysis of 7 leads to easily accessible 9.The benzo condensed phosphonates 12 and 13 are formed according to the solvent; a higher boiling medium should be used to obtain 15 and 17. Keywords: Phosphonates; Cycloalkylation and benzo condensed cycloalkylation.
