Production of allylsulfone |
| abstract |
PURPOSE: To obtain the titled compound useful as a drug intermediate in high yield, by reacting a readily obtainable tertiary allyl halide with a phenylsulfinate in the presence of a halogenated tetraalkylammonium salt in an anhydrous system. n CONSTITUTION: A tertiary allyl halide shown by formula I (X is Cl, Br or I) and/or a primary allyl halide shown by formula II is reacted with a phenylsulfinate shown by formula III (R is H or lower alkyl; m is Na or K) in the presence of a halogenated tetraalkylammonium salt in an anhydrous system to give an allylsulfone shown by formula IV (double bond does not distinguish stereospecificity). The compound shown by formula IV is useful as a synthetic intermediate for vitamin A acetate. n COPYRIGHT: (C)1988,JPO&Japio |
