资源简介：
Efficient conversion of α-mercapto
ketones 1 with activated alkenes 2 into
S-heterocycles was developed
with Sn(Oct)2–2MeOH acting as a catalyst. Two types
of products, dihydrothiophene 3 and thiolane 4, were obtained. The selectivity of the products was dependent on
the reaction temperature and on the rearrangement of the S-heterocycles
from 3 to 4 under heating conditions. The
dihydrothiophenes 3 were transformed into useful thiolactones 6–8 and thiophene 9.
