Application of Oxathiazolidine-S-oxide Chemistry to the Large-Scale Single-Step Synthesis of an O-Arylethanolamine
摘要:
Alternative routes to the arylethanolamine subunit of a development drug have been investigated. The selected route, involving O-alkylation of a phenol using N-benzyloxathiazolidine-S-oxide, was developed to give a process used successfully for pilot plant manufacture.
