실험 절차

The reaction of 7.12 g (34.8 mmoles) of aluminum isopropoxide in 100 ml of toluene with 1.5 g (5.8 mmoles) of 6-(carbethoxymethyl)-3-n-butyl-2-cyclohexen-1-one was conducted in a similar manner to the synthesis of 3a,4,5,7a-tetrahydro-2(3H)-benzofuranone described in Example I. The crude material was purified by crystallization from hexane to yield 1.04 g (84%) of cis 6-phenyl-3a,4,5,7a-tetrahydro-2(3H)-benzofuranone, mp 90°-92° C. NMR and IR confirm the structure of the compound.
