Abstract: Abstract A new synthetic method to construct [b]-fused BODIPY derivatives through PtCl2-catalyzed cycloisomerization reaction of peripherally phenylacetylene substituted BODIPYs is reported. Electron donating methoxy group facilitate both the 6-endo and 5-exo cyclization procedure to produce… read more here.

Abstract: Rhodium-catalyzed C-H/N-H [5 + 2] annulations of 8-(pyrrol-2-yl)-appended boron-complexed dipyrromethenes (BODIPYs) with internal alkynes have been established to afford a series of azepine-fused BODIPYs with good yields and excellent regioselectivity, in which the pyrrol-2-yl unit… read more here.

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.
