    • General Procedure for the BuTeBr3 Cyclizations To a solution of 0.50 mmol of the appropriate (Z)-selenoenyne in MeCN (5 mL) was added BuTeBr3 (0.233 g, 0.55 mmol, The reaction mixture was allowed to stir at r.t. for the time showed in Table 3. After this time, EtOH (5 mL) and NaBH4 (0.037 g, l mmol) were added under vigorous stirring (gas evolution was observed during this addition, The reaction mixture was stirred at r.t. for one additional hour, diluted with EtOAc (20 mL) and washed with H2O (10 mL) and brine 3 x 10 mL, The organic layer was dried over anhyd Mg2SO4 and concentrated under vacuum to yield the crude product, which was purified by flash chromatography on silica gel using hexane as the eluent. Analysis of the 1H NMR and 13C NMR spectra showed that all the obtained products presented data in full agreement with their assigned structures. Selected Spectral and Analyt
