Abstract:The rearrangement of dithiolanes and dithianes to access disulfide‐linked‐dithioesters under visible‐light photoredox catalysis via controlled C−S bond cleavage has been disclosed. Unlike, the usual deprotection of dithioacetals to corresponding aldehydes under the oxidative conditions, we observed unique regioselective oxidative reactivity of five and six membered cyclic dithioacetals to form disulfide‐linked‐dithioesters by exchanging DMAP and imidazole bases. The generality of the protocol has been demonstr… Show more
