The design and synthesis of a simple, selective and efficient turn-off fluorescent Au3+ probe, namely, diethyl 1-phenyl-2,5-di(thiophen-2- yl)-1H-pyrrole-3,4-dicarboxylate (1), are highlighted. To our best knowledge, this is the first example of nonreaction-based fluorescent Au3+ probes.

A series of 1-substituted diethyl 1H-pyrrole-3,4-dicarboxylates 4a - o were prepared in 14-93% yield by acid-catalysed treatment of diethyl 2,3-bis[(E, E)-(dimethylamino)-methylidene]succinate (2) with various aliphatic and (hetero)aromatic primary amines 3a - o. The configuration of the C=C double bonds in the bis-enaminone 2 was determined by 1H NMR and HMBC spectroscopy.
Practical one-pot sequential procedure for the preparation of N-arylated 3,4-disubstituted pyrroles from alkenes

scheme or table, p. 3897 - 3901 (2009/04/07)
By using tBuONa and Cs2CO3 as a mixed base, van Leusen pyrrole synthesis and copper-catalyzed N-arylation of pyrrole proceeded sequentially in a single flask to give N-arylated 3,4-disubstituted pyrroles smoothly. Thus, a series of desired N-arylated pyrroles were prepared directly from the electron-deficient alkenes.
