HIGHLY STEREOSELECTIVE CLAISEN REARRANGEMENT OF VINYL ETHER OF 1-(1-HYDROXYETHYL)-2-METHYL-3-ALKYLCYCLOPENTENE. A ROUTE TO CIS- AND TRANS(1E)-ETHYLIDENE-8-METHYLHYDRINDAN-5-ONE.

The highly stereoselective Claisen rearrangement of the α-isomer of vinyl ether of 1-(1-hydroxyethyl)-2-methyl-3-alkylcyclopentene introduces the trans stereochemistry between C(8)methyl and C(9)hydrogen and the geometry of E-olefin, necessary for a synth
