- Preparation of isopropylidene acetals from butane-1,2,4-triol and its cyclopropane congeners
-
Features of isopropylidene acetal synthesis from butane-1,2,4-triol and its cyclopropane congeners were studied. Procedures for the preparation and purification of the respective acetonides have been developed.

- SOME NEW ASPECTS OF TRANSKETALIZATIONS AND ACETONATIONS OF 1,2,n-TRIOLS (n = 3, 4 ) USING 2,2-DIMETHOXYPROPANE AND 2-METHOXYPROPENE IN THE PRESENCE OF BUTYLTIN CHLORIDES: BuSnCl3, Bu2SnCl2, Bu3SnCl, (Bu2SnCl)2O AND BuSn(OH)2Cl
-
Transketalizations and acetonations of 2,2-dimethoxypropane and 2-methoxypropene, respectively, using 1,2,3-propane and 1,2,4-butanetriol have been carried out, at room temperature, under the mediation of the following butyltin chlorides: BuSnCl3, Bu2SnCl2, Bu3SnCl, (Bu2SnCl)2O and BuSn(OH)2Cl.The main products are represented by 1,3-dioxolane derivatives when the four mediators are employed.When BuSn(OH)2Cl is employed, particularly in the case of acetonation, a mixture of dioxolane derivatives together with two acetone ketals containing 1,2-O-isopropylidenetriol residues is obtained.
