WebNov 21, 2024 · The click reactions involving the addition of thiols have been reviewed. Thiol-ene click chemistry, particularly applicable to polymer chemistry, was reviewed by Hoyle and Bowman . The Bowman team also reviewed the thio-Michael addition click reaction as another powerful tool in material chemistry. WebApr 13, 2024 · Michael addition of thiol to 5MPs occurs rapidly, cleanly, and does not generate a stereocenter. The conjugates efficiently release thiols via retro-Michael reaction in alkaline buffer (pH 9.5) or via thiol exchange at pH 7.5. This unique property makes 5MPs valuable for the controlled release of conjugated cargo and temporary thiol protection.
