One-pot synthesis and functionalization of polyynes via alkylidene carbenoids

A one-pot, two-step method for the synthesis of diynes and triynes is reported. The reaction of a dibromoolefinic precursor with BuLi effects a Fritsch-Buttenberg-Wiechell rearrangement and generates a lithium acetylide intermediate, which is then trapped

Synthesis of naturally occurring polyacetylenes via a bis-silylated diyne

A straightforward synthesis of a series of naturally occurring polyacetylenes has been developed, including the montiporynes A and C, possessing cytotoxic activity against several human solid tumor cells, the atractylodin, with antibiotic activity against Escherichia coli, and triynes, which display insecticidal activities, starting from the readily available 1,4-bis(trimethylsilyl)-1,3-butadiyne.

A one-pot synthesis and functionalization of polyynes

A one-pot synthesis and derivatization of diynes and triynes is reported. The polyyne framework is formed from a dibromoolefin precursor based on a carbenoid rearrangement, and the resulting Li-acetylide is then trapped in situ with an electrophile to pro
