Vinyl sulfides represent an important class of compounds in organic chemistry and materials science. Atom-economic addition of thiols to the triple bond of alkynes provides an excellent opportunity for environmentally friendly processes. We have found that well-known and readily available Pd-NHC complex (IMes)Pd(acac)Cl is an efficient catalyst for alkyne hydrothiolation. The reported technique provides

A new stereocontrolledtotal synthesis of the (1R,5S,7R)-exo-6,8-dioxabicyclo[3.2.1]oct-3-ene skeleton of the Mus musculus pheromone has been achieved via an asymmetric intermolecular Diels–Alder reaction and an intramolecular conjugated addition, controlled by a chiral auxiliary.
