Vinylcyclopropanes (VCPs) are commonly used in transition-metal-catalyzed cycloadditions, and the utilization of their recently realized reactivities to construct new cyclic architectures is of great significance in modern synthetic chemistry. Herein, a p

An organobase-controlled, divergent cascade reaction to construct spirocyclohexene indane-1,3-diones and coumarin-fused cyclopentanes is reported. The cascade reaction is triggered by the 1,6-addition of 3-homoacylcoumarins to the indanedione-derived acce

We present the details of an organophosphine-catalyzed Morita-Baylis-Hillman-type reaction of activated alkynes. The outcome is an intramolecular hydroacylation of α,β-ynones leading to the formation of 1,3-cyclopenta-, cyclohepta-, and cyclooctadione-fused arenes and heteroarenes. In addition, during the course of the investigation, a phosphine-catalyzed intramolecular aldol reaction of keto-ynones via δ′[C(sp3)-H]-functionalization was discovered, and a new annulation event comprising of a ω′[C(sp3)-H]-functionalization of α,β-ynones was also uncovered. The mechanisms governing these processes have been thoroughly elucidated.

In this contribution, the high-yield preparation and optical properties of some donor-acceptor butadiene dyes, generated by coupling of different 1,1-diaryl-2-propyn-1-ols with indan-1,3-dione, are presented. The reactions, which involve the initial Meyer
