sesquiterpene, (+)-axisonitrile-3. Three key features of this synthesis are: (i) non-Evans syn-aldol reaction of an isovaleric acid derivative bearing a chiral oxazolidinethione and crotonaldehyde with high diastereoselectivity, (ii) Claisen rearrangement of alkenyl dihydropyran affording spiro[4.5]decane with requisite functionalities, and (iii) highly stereoselective reduction in the sterically congested
