Abstract
A visible-light-induced aerobic oxidative [2+3] cycloaddition reaction between glycine derivatives and thiiranes has been disclosed, which provides an efficient and atom-economical strategy for the rapid synthesis of thiazolidine-2-carboxylic acid derivatives and the post-modification of glycine-derived dipeptides under mild conditions with good yield and high diastereoselectivities. A preliminary mechanistic study favors a pathway involving a cooperative photoredox catalysis and iron catalysis.

Abstract
An unprecedented H2S release from cysteine esters and amides (CysO/NHR) under physiological conditions was discovered and the plausible mechanism was proposed. Alkylation of the amino moiety of cysteine esters enables the H2S release to be tuned and further provides support to the mechanistic insights. This discovery not only provides new insights into several fundamental science issues including non-enzymatic H2S-produced pathways, but also inspires new tunable cleavable motifs for sustained release of arylthiols and even for prodrug design.
