1,2-Cyclic Sulfamidates as Versatile Precursors to Thiomorpholines and Piperazines
摘要:
Graphics1,2-Cyclic sulfamidates undergo regiospecific nucleophilic displacement with either methyl thioglycolate or a-amino esters, followed by lactamization (thermal, base-mediated, or cyanide-catalyzed), to give thiomorpholin-3-ones and piperazin-2-ones.
