The chemical synthesis of racemic diacyloxypropylphosphonylcholines having octanoyl, myristoyl, oleoyl and stearoyl groups is described. The route involved reaction of dioactanoyloxy-, dimyristoyloxy-, dioleoyloxy-, and distearoyloxypropyliodide with tris(trimethylsilyl) phosphite to yield {he corre

## Abstract Lithiation of 4โbenzyloxyโ2โbromotoluene and subsequent quenching of the lithiated product affords 4โbenzyloxytolueneโ2โt which is oxidized directly to 4โbenzyloxybenzaldehydeโ2โt with ceric ammonium nitrate. Transformation of the aldehyde 6 by standard procedures affords DLโtyrosineโ2โฒ
A synthesis of the title compound from /13Clparaformaldehyde and [15N)ammonium chloride V f 8 ethyl 2-(1 ,3-/2-13Cldithianyl) acetate 3a is described. Ethyl/3-13C13-oxopropanoate derived in sl'tu from 3a was converted by a stepwise Strecker procedure to DL-[ 2-13C,15Nlaspartic acid 7a.
