Pseudomonas putida oxidation of benzene affords cis-3,5-cyclohexadiene-1,2-diol (2) which is used as a novel precursor for the synthesis of D- and L-myo-inositol 1,4,5-triphosphates, (-)-(1) and (+)-(1).The versatility of this approach to functionalised cyclitols is illustrated in the synthesis of myo-inositol 1-phosphate (19), 6-deoxy, 6-deoxy-6-fluoro, and 6-deoxy-6-methyl myo-inositols (31), (37) and (43), and their 1,4,5-trisphosphate derivatives (33), (39) and (45).

Haloform reaction of 4-alkoxy-1,1,1-trichloro-3-buten-2-ones, which can be obtained by acylation of enol ethers, gives 3,3-dialkoxypropanoic esters.Transacetalization of ethyl 3,3-diethoxypropanoate with 2,2-dimethyl-1,3-propanediol, followed by reduction and oxidation with DMSO/oxalyl chloride yields a monoprotected malonaldehyde. 4-Ethoxy-2-oxo-3-butenoates are synthesized either by acylation of enol ethers with alkoxalyl chlorides or by Claisen condensation of alkyl pyruvates with orthoesters.
