Pummerer-type reaction was carried out with α-acyl sulfides and polymer-supportedbis(trifluoroacetoxyiodo)benzene (PSBTI) instead of α-acyl sulfoxides to prepare 2,3-dihydro-5H-1,4-benzoxathiepins.

in designing molecular motors and machines that exploit random thermal fluctuations for directional motion with energy input. To integrate ratchet mechanism into artificial systems, precise molecular design is a prerequisite to control the pathway of relative motion between their subcomponents, which is still a formidable challenge. Herein, we report a straightforward method to control the transportation
