Allenic phosphonate reagent compositions are described which have the formula (1) wherein R and R' = C1 - C4 alkyl groups, or R, R' = (CH2)n (n = 2 or 3) or [CH2C(CH3)2CH2]. Also described are methods for forming such allenic phosphonates from ethynyl- beta -ionol, and for converting these allenic compounds to allylic phosphonate compounds which can be used in the synthesis of a variety of biologically-active materials. |
