The first access to chiral homoallylic-homopropargylic amine bearing two contiguous stereocenters has been well accomplished via zinc-promoted aza-Barbier reaction. N-tert-Butanesulfinyl ketimines are well-tolerated substrates, providing the tertiary amin

A golden opportunity: A novel gold-catalyzed oxidative ring-expansion of unactivated cyclopropylalkynes using Ph2SO has been developed (see scheme). For substrates bearing a donor group at the cyclopropane ring, preliminary results reveal a distinct cleavage of the cyclopropane unit; such a ring cleavage is further applicable to the synthesis of 2H-pyrans.
