摘要

Starting from the ketones 3 and 4 the synthesis of six spiro ethers with an l-oxaspiro [4.5] decane skeleton is described. Five of them, 9a, b, 10a, 19 and 19 represent typical partial structures of the sesquiterpenoid spiro ether 1. The unambiguous synthesis of 1 shows a previous assignment of “'bisabolene oxide “'to structure 1 to be wrong.
