Narala, Siva Ganesh; Nagalatha, G.; Venkat Narsaiah, A. published the article 《Stereoselective total synthesis of C2-symmetric natural products pyrenophorol and its derivatives》. Keywords: pyrenophorol stereoselective synthesis regioselective epoxide opening reduction Pinnick oxidation; Mitsunobu dilactonization pyrenophorol stereoselective synthesis; CBS reduction; Macrodiolide; Pinnick oxidation; antimicrobiol agent; dilactonization.They researched the compound: (S)-2-Bromosuccinic acid( cas:20859-23-8 ).Recommanded Product: 20859-23-8. Aromatic heterocyclic compounds can be divided into two categories: single heterocyclic and fused heterocyclic. In addition, there is a lot of other information about this compound (cas:20859-23-8) here.
A stereoselective total synthesis of 16-membered C2-sym. macrodiolide pyrenophorol (I, R = H), tetrahydropyrenophorol (II) and 4,4-diacetylpyrenophorol I (R = COMe) have been accomplished. The synthesis started from com. available L-Aspartic acid and the key reactions involved are regioselective epoxide opening, CBS reduction, Pinnick oxidation and Mitsunobu dilactonization.
Compounds in my other articles are similar to this one((S)-2-Bromosuccinic acid)Recommanded Product: 20859-23-8, you can compare them to see their pros and cons in some ways,such as convenient, effective and so on.
