摘要

and N-(tert-Butoxycarbonyl)-S-oxo-Sn-butyl-L-cysteinol (25). A cooled (COz/2-propanol) solution of the n-butyllithium-TMEDA complex, prepared by adding TMEDA (523 mg, 0.68 mL, 4.5 mmol) to a solution of n-butyllithium in hexane (4.5 mmol), was added to a stirred, cooled (-78" C) solution of the sultine 14a (383 mg, 1.5 mmol) or 21b (331 mg, 1.5 mmol) in 5 mL of freahly distilled, dry THF. The reaction mixture was stirred at-70 OC for 30 min and ...
