WebLithium 2,2,6,6-Tetramethylpiperidide (LiTMP, pKa. 37).[4, 8, 9] This is the most potent and least nucleophilic of the amide bases. It is kinetically faster than LDA, and will smoothly do many deprotonations not possible with LDA. Interference by the amine (e.g. in acylations) is minimal because of high steric hindrance.
