| Abstract: | The Diets-Alder reaction of levoglucosenone with piperylene catalyzed by ZnCl2 proceeds regio- and stereoselectively to give thesin-cis-adduct3; the thermal reaction yields an epimeric mixture of compound3 withsin-trans-adduct4 in the ratio of 4 : 1.Translated fromIzvestiya Akademii Nauk.
