Conclusions
-
1.
δ-Tetrahydrofurylalkanols were synthesized by the conversion of γ-tetrahydrofurylalkanols to the corresponding bromides and Grignard reaction of the latter with aliphatic aldehydes. δ-Tetrahydrofurylalkanols were obtained for the first time as a result of these reactions.
-
2.
The tetrahydrofuran ring of δ-tetrahydrofurylalkanols undergoes isomerization with an opening of the ring at the C-O bond furthest away from the side-chain substituent. Homologs of tetrahydropyran are formed as a result of the cyclodehydration of 1, 5-diols.
