The crystal structure of (+/-)-1,2;4,5-di-O-cyclohexylidene myo-inositol, refined to R=2.9%, shows interestingly disordered (flip-flop) hydrogen bonding. The higher reactivity of the 1/3 positions (rather than 4/6) has been evaluated using semi-empirical calculations. This diol has been phosphorylated with (2R,4S,5R)-2-chloro-3,4-dimethyl-5-phenyl-1,3,2-oxazaphospholidin-2-one and the diastereoisomer derived from phosphorylation at the 3-position was isolated by crystallisation, Deprotection with TFA/H2O then H-2/Pd-C afforded myo-inositol 3-phosphate in only four steps from myo-inositol.
