TBAF-catalyzed cyclization of 6-hydroxyhex-2-ynoates and 7-hydroxyhept-2-ynoates
Wang, Xiao Qing,Jia, Ping Jing,Liu, Su Ping,Yu, Wei
experimental part, p. 931 - 934 (2012/01/11)
Tetrabutyl ammonium fluoride (TBAF) was found to be capable of catalyzing the intramolecular hydroalkoxylation of 6-hydroxyhex-2-ynoates and 7-hydroxyhept-2-ynoates. The reaction could be used to prepare 2,5-substituted THF rings and 2,6-substituted THP rings.

Novel compounds of formula (1.0) are disclosed. In Formula (1.0) a represents N or NO, R and R are halo, R and R are independently H or halo provided that at least one is H, X is C, CH or N, and T represents a five or six membered heterocycloalkyl ring having one or two heteroatoms selected from S or O. Also disclosed are methods of inhibiting farnesyl protein transferase and methods for treating tumor cells.
Intermolecular copper-catalyzed carbon-hydrogen bond activation via carbene insertion
Diaz-Requejo, M. Mar,Belderrain, Tomas R.,Nicasio, M. Carmen,Trofimenko, Swiatoslaw,Perez, Pedro J.
, p. 896 - 897 (2007/10/03)
A series of catalysts of general formula TpXCu (TpX = homoscorpionate ligand) promote the insertion of :CHCO2Et (ethyl diazoacetate as the carbene source) into the C-H bonds of cycloalkanes and cyclic ethers in moderate to high yield. A correlation between the steric hindrance of these catalysts and the yield of the transformation has been observed. Copyright

β-Alkoxyacrylates in radical cyclizations: Remarkably efficient oxacyle synthesis
Lee, Eun,Tae, Jin Sung,Lee, Chulbom,Park, Cheol Min
, p. 4831 - 4834 (2007/10/02)
β-Alkoxyacrylates were found to be exceptionally efficient radical acceptors in radical-mediated intramolecular cyclizations. For example, reaction of 5-bromo-2-pentanol with ethyl propiolate, tributylstannane-mediated radical cyclization, and hydrolysis yielded (±) (cis-6-methyltetrahydropyran-2-yl)acetic acid, a known component of civet.
