DOI: 10.1002/cctc.201900089
Abstract: Gold‐catalyzed cycloisomerization reactions have been explored using guanidinium functionalized M12L24 nanospheres that strongly encapsulate gold complexes functionalized with a sulfonate group through hydrogen bonds. As the M12L24 nanospheres can bind up to 24 gold complexes,… read more here.

DOI: 10.1021/acs.orglett.2c00534
Abstract: A palladium-catalyzed cycloisomerization of 2-ethynylbiaryls to 9-methylidene fluorenes is described for the first time. The cycloisomerization of 2-ethynylbiaryls proceeded smoothly in the presence of weak acid at low temperature to afford 9-methylidene fluorenes in satisfactory… read more here.

DOI: 10.1039/c7qo00272f
Abstract: An efficient method for the synthesis of C2-spiropseudoindoxyls which are common structural units prevalent in indole alkaloids was developed. A study of the mechanism indicated that this protocol involved a Pd-catalyzed 5-exo-dig nitroalkyne cyclization and… read more here.

DOI: 10.1039/d0sc01054e
Abstract: Here we report gold(i)-catalyzed cycloisomerization as a new powerful synthetic tool for the preparation of π-extended BODIPY derivatives. The catalytic system PPhF3AuCl/AgSbF6 enables the synthesis of [b]-[2,1]naphtho-fused-BODIPYs (2a–2c) under mild conditions, in excellent yields and… read more here.
