Synthesis and Structural Study of (+)-5-Acetyl-6-methyl-5p-tolylsulfinyl-3a,4,5,6-tetrahydro (3H)-Benzofuran-2-one
摘要:
an efficient synthesis of the title compound has been developed from 3-phenyl suffonylpropanoic acid via the butenolide 2. The key synthetic step is a Diels-Alder reaction. A mechanism is suggested.
