Chalyk, Bohdan published the artcileUnexpected Isomerization of Oxetane-Carboxylic Acids, Related Products of esters-buliding-blocks, the publication is Organic Letters (2022), 24(26), 4722-4728, database is CAplus and MEDLINE.
Many oxetane-carboxylic acids were found to be unstable. They easily isomerized into new (hetero)cyclic lactones while being stored at room temperature or slightly heated. Chemists should keep in mind the high instability of these mols., as this could dramatically affect the reaction yields and led to neg. results (especially in those reactions that require heating).
Organic Letters published new progress about 1207175-04-9. 1207175-04-9 belongs to esters-buliding-blocks, auxiliary class Oxetane,Ester, name is Ethyl 2-(oxetan-3-yl)acetate, and the molecular formula is C7H12O3, Related Products of esters-buliding-blocks.
