実験手順

This compound was prepared analogously to (5), starting from thiolacetic acid and methylvinylsulphone, leading to the intermediate sulphone (47%), treating subsequently with the tin oxide to give the required product (6) (41%). All spectroscopic and analytical data were consistent with the proposed structures.
