| Abstract: | The enolate of CpMo(CO)2(syn-η3-1-C3H4COCH3) generated with lithium diisopropylamide in THF undergoes diastereoselective aldol reaction with benzaldehyde; the alcohol thus formed has been utilized for stereoselective synthesis of 1.5-diphenyl-2-vinyl-pentan-1,3,5-triol and 2-vinyl-3-hydroxyl-5-phenyl-tetrahydrofuran. |
