Oxa-thia-spiro-decene Derivatives

The crystal structures of (5R)-(10-methyl-1-oxa-4-thiaspiro[4.5]dec-9-en-9-yl)phenyl(S)-methanol, C₁₆H₂₀O₂S, (1), and 1(S)-[(5R)-10-methyl-1-oxa-4-thiaspiro[4.5]dec-9-en-9-yl)ethyl 4-methoxybenzoate, C₁₉H₂₄O₄S, (2), are composed of independent molecules separated by normal van der Waals distances. The molecular dimensions in both structures are normal. The hydroxyl and heterocyclic ring O atoms exhibit a short intermolecular hydrogen bond of the order of 2.814 (4) Å in (1) forming a chain of molecules along the c axis.
