Mitsunobu Reaction - Organic Chemistry

WebIn more alkaline conditions (pH >8.5), the reaction favors primary amines and also increases the rate of hydrolysis of the maleimide group to a non-reactive maleamic acid. Maleimides do not react with tyrosines, histidines or methionines. WebThe Mitsunobu Reaction allows the conversion of primary and secondary alcohols to esters, phenyl ethers, thioethers and various other compounds. The nucleophile employed should be acidic, since one of the reagents ( DEAD, diethylazodicarboxylate) must be protonated during the course of the reaction to prevent from side reactions. bitdefender pros and cons https://prioryphotographyni.com
