Abstract
As an extension of Chap. 1 and, in order to obtain a clearer picture of the intertwined reaction pathways at play in the gold(I)-catalyzed addition of carbonyl compounds. The gold-catalyzed cycloisomerization of 1,6-enynes of type II-22 bearing a carbonyl group at the alkyne moiety was examinazed. The reaction led to the unexpected formation of cyclobutene compounds of type II-23. As a further development of cyclobutene synthesis, two more examples presenting the cyclobutene motif (II-24) were obtained via gold(I)-catalyzed cyclization of 1,8-enynes.

Results obtained in collaboration with Masaki Sekine (visiting PhD student from the group of Prof. Eiichi Nakamura, Tokyo University, Japan)
PPh3-bound polymer was added before purification to completely remove the gold(I) complex
A 1 M solution of Et3N in cyclohexane was added, followed by filtration through a plug of Celite to quench the gold(I) complex
