A polycyclic collapse: Use of a carefully designed acyclic intermediate participated in a cascade reaction that formed the entire core of the polyketide‐derived dalesconols in a single flask (see scheme). A number of additional and carefully controlled synthetic operations completed an expeditious synthesis of both of these highly bioactive natural products as well as structural congenors.

An efficient rhodium/olefin–sulfoxide catalyzed asymmetric conjugateaddition of organoboronic acids to a variety of nitroalkenes has been developed, where 2-methoxy-1-naphthyl sulfinyl functionalized olefin ligands have shown to be highly effective and are applicable to a broad scope of aryl, alkyl, and heteroaryl nitroalkenes.
