The invention discloses a method for fluoroalkylation of enamines with a fluoro alkyl halide in the presence of a base.

The invention discloses a method for fluoroalkylation of enamines with a fluoro alkyl halide in the presence of a base.

The present invention relates to a process for the preparation of tapentadol and analogs or compounds or stereoisomers of formula (I), Formula I wherein, A is aryl, heteroaryl, and cycloalkyl; R is H, OH, OR.sup.1, halogen, C.sub.1-C.sub.12 alkyl, cycloalkyl, aryl or heteroaryl; R.sup.1 is C.sub.1-C.sub.12 alkyl, cycloalkyl, aryl or heteroaryl, wherein each of these groups may further be substituted with one or more substituent selected from H, OH, halogen, CN, NO.sub.2, C.sub.1-C.sub.4 alkyl or phenyl. Further, the multi-step process involves no column chromatography purification until the very last step. This makes this process highly commercially viable and industrially useful.
