Formation of tricyclolactone-1,3-dioxane from Grieco lactone in the Prins reaction: Formation of tricyclolactone-1,3-dioxane from Grieco lactone in the Prins reaction. Narep, M.; Valimae, T.; Lopp, M.; Lille, U. (Inst. Chem., Tallinn, USSR). Eesti NSV Tead. Akad. Toim., Keem., 35(2), 157-9 (Russian) 1986. CODEN: ENTKDR. ISSN: 0201-8128. DOCUMENT TYPE: Journal CA Section: 28 (Heterocyclic Compounds (More Than One Hetero Atom)) Treating Grieco lactone (I) with 30% CH2O in AcOH and 100% H2SO4 100 h at 80° gave 43% lactone II via intermediate lactone III (R = CHO). 54483-22-6 and 76704-05-7 are just another two chemicals used in this study. Treating III (R = H) with 100% H2SO4, paraformaldehyde, and AcOH 70 h at 80° gave 28% III (R = Ac) and 68% lactone II. .
