SOLID SUPPORTED SYNTHESIS OF SULFONATED 2-OXOPIPERAZINES

摘要

The subject invention involves processes for making 2-oxopiperazine and homologous compounds using a solid support resin by (a) removing the protecting group from a N-protected amino acid ester of the resin (if present), (b) reacting the resulting unprotected resin ester with a sulfonyl chloride, (c) reacting the resulting intermediate with a N-protected amino alcohol, (d) removing the N-protecting group from the N from the amino alcohol, and (e) cleaving/cyclizing the product from the resin.
