摘要

A general procedure for chemoselective acylation of substituted aminophenols has been developed. The N-acylated products 7 and 10a-h were prepared by treating the aminophenols with 3 (trimethylacetyl)-1, 3-thiazolidine-2-thione (1) in refluxing THF in 70– 100% yield. The esters 8 and 13d, b, j of 3-and 4-amino phenols could be obtained in 70– 94% yield by treating with NaH and 1.
