Similar to 136, furan 137 was also prepared via the oxazole route. Yun Yang, a student from Guangzhou Institute of Chemistry, thermolyzed oxazole 139 and bis(tri-n-butylstannyl)acetylene 155 in a sealed tube to afford a separable mixture... 

Structural characterizations of macrocycUc aromatic sulfide oUgomers were studied jointly at Guangzhou Institute of Chemistry and McGUl University Department of Chemistry. The studies used matrix-assisted laser desorption and ionization time of flight mass spectroscopy (MALD ITF-MS), which the researchers said was a powerful tool to analyze the macrocyclics [13].

A similar chemistry was disclosed in a patent appHcation from Guangzhou Institutes of Biomedidne and Health (15CN104860914) where a series of SFs-substituted chromenes was prepared and claimed as being effident and selective cyclooxygenase-2 (COX-2) inhibitors. Thus cyclocondensation of 4-SF5- or S-SFs-salicyhc aldehydes (116 or 114a) with ethyl 4,4,4-trifluorocrotonate provided racemic 7-SF5- or 6-SF5-2-CF3-2H-chromene-3-carboxylates ( )-117 and ( )-118, which were converted to the corresponding carboxyHc adds ( )-119 and ( )-113a (Scheme 31).
