THE SYNTHESIS OF ALLYLIC PHOSPHATE DERIVATIVES OF TRANS ZEATIN

Article abstract of DOI:10.1016/S0040-4020(01)89248-6

Phosphitylation of the allylic hydroxy group in 9-tetrahydropyranyl trans-zeatine with salicyl chlorophosphite gives the allyl phosphonate monoester 5, which can be readily converted into the corresponding phosphate 7, methylphosphate 8 or thiophosphate 9.After cleavage of the tetrahydropyranyl group under mild acidic condition allylic phosphate derivatives of trans-zeatin are obtained.
