Using the Mitsunobu reaction as a key step, a general and efficient method for the synthesis of EDOT monomers has been developed. Novel substituted EDOTs and the first chiral derivatives were generated in high yields.
caffeic acid phenethyl ester(cape) suppresses the growth of transformed cells such as human breast cancer cells, hepatocarcinoma , myeloid leukemia, colorectal cancer cells, fibrosarcoma, glioma and melanoma. a group of heterocyclic esters of caffeic acid was synthesized using mitsunobu reaction and the esters were subjected to further structural modification by electrooxidation of the catechol...
A novel protecting group directed diversity leading to the synthesis of bridged bicyclic and six-membered iminocyclitols from a common carbohydrate derived diamino triol under Mitsunobu conditions is reported. When the intramolecular cyclization of benzoyl derivative 16 was carried out under Mitsunobu conditions, an unprecedented one-pot domino intramolecular "cyclization-N→O benzoyl migration-...
Reaction of hexa-N-Boc neomycin B with TPP and DIAD in toluene results in the formation of an epoxide in ring IV, not an aziridine or azetidine as previously reported.
Hydroxyindoline-derived scaffold, 9, was synthesized with the goal of generating a library of indoline-based natural product-like tricyclic derivatives to be utilized as small-molecule chemical probes. The tricyclic ring was obtained by a Mitsunobu reaction of the N-nosyl amino acid conjugate with the primary hydroxyl group. The solid-phase synthesis was achieved by immobilizing scaffold 9 onto...
reaction and has been applied widely in organic synthesis. In the Mitsunobu reaction, a unique dehydration occurs between alcohols and various Brønsted-Lowry acids (HA) utilizing the combination of diethyl azodicarboxylate and triphenylphosphine (Fig. 1). However, the reaction has a serious limitation (so-called the restriction of pKa); the acidic hydrogen in HA has to have pKa of less than 11 ...
