摘要:
The resolution of 1-i-butyl-3-methyl-3-phospholene 1-oxide was studied applying TADDOL [(-)-(4R,5R)-4,5-bis(diphenylhydroxymethyl)-2,2-dimethyldioxolane], spiro-TADDOL [(-)-(2R,3R)-,,,-tetraphenyl-1,4-dioxaspiro[4.5]decan-2,3-dimethanol], or the acidic and neutral Ca2+ salts of (-)-O,O-dibenzoyl- and (-)-O,O-di-p-toluoyl-(2R,3R)-tartaric acid as the resolving agent. The absolute configuration of the P-asymmetric center was determined by circular dichroism spectroscopy and related quantum chemical calculations. In one instance, the single crystal of the diastereomeric complex incorporating i-butyl-3-phospholene oxide and spiro-TADDOL was subjected to X-ray analysis, which suggested a feasible hypothesis for the efficiency of the resolution process under discussion that may be an example for the solvent-inhibited resolution.
