Racemization-Free Synthesis of S-Alkylated Cysteines via Thiol-ene Reaction
摘要:
[GRPAHICS]Treatment of differently protected and unprotected cysteines with a variety of alkenes in the presence of a radical initiator (AIBN) afforded the corresponding S-alkylated cysteines in high yields and without racemization.
