Essential oil variability of Thymus zygis growing wild in southeastern spain

Variations in the essential oils of Thymus zygis ssp. sylvestris and T. zygis ssp. gracilis growing in southeastern Spain were examined. Some hybrids with other species of thyme were detected, and the chemical influence of both parentals was demonstrated. The most common chemotype was thymol, although a pure linalool chemotype was recorded.

Oxirane ring-opening with alcohol catalyzed by organotin phosphate condensates. Complete inversion at tertiary and benzylic centers

Regio- and stereospecific ring-opening ofchiral oxiranes has been effected by organotin phosphate condensates catalyst. Alcohols attack on the tertiary and benzylic positions exclusively. Despite seemingly acidic character of the catalyst in terms of regioselectivity the chiral centers are completely inverted. The new methodolgy is applied to synthesis of enantiomerically pure linalool and to conversion of commercially available (R)-styrene oxide into the (S)-counterpart.
