Cyclobutene formation in PtCl2-catalyzed cycloisomerizations of heteroatom-tethered 1,6-enynes

Aza(oxa)bicyclo[3.2.0]heptenes are accessed through the PtCl 2-catalyzed cycloisomerizations of heteroatom-tethered 1,6-enynes featuring a terminal alkyne and amide as the solvent. It is shown that the weak coordinating properties of the solven

Annelated Cyclobutanes by Fe-Catalyzed Cycloisomerization of Enyne Acetates

Cationic Fe complexes of the general type [(Ph3P)2Fe(CO)(NO)]X (X=BF4, BArF4) catalyze the redox-neutral cycloisomerization of 1,6- and 1,7-enyneacetates to afford bicyclic cyclobutanes under mild conditions in good yields and diastereoselectivities.

Versatile Cyclisation Reactions Using Selenoboranes

Tris(phenylseleno)borane and tris(methylseleno)borane reacted with terminal acetylenes to afford (Z)-vinyl selenides.This reaction was initiated by oxygen and the intermediates were vinyl radicals.This radical reaction could be applied to the intramolecular free radical cyclisation of enynes and some heterocycles and carbocycles were synthesised.This novel method could be also employed in the synthesis of α-kainoid derivatives.
