    • 2 was added dropwise. The reactions were stirred at −78° C for 2h and allowed to gradually warm toward room temperature over 1 h. They were maintained at room temperature until complete (as monitored by thin layer chromatography, products at Rf = 0.68 in 4:1 hexane/ethyl acetate) before being treated with water. The aqueous layer was [[Truncated]]
