Total synthesis of AIB AIB (1), PM (2) and its one-carbon lower homologue YM (3), amicoumacin C (4), bacilosarcins A (5), and bacilosarcins B (6) (Scheme 1) having in common the dihydroisocoumarin ring system possess interesting biological by: 6.
An enantioselective total synthesis of AIB (1), a gastroprotective substance isolated from a culture broth of Bacillus pumilus AI, was performed in high overall yield.
In this synthesis, the dihydroisocoumarin part 14 and the dihydroxyamino acid part 20 were both assembled from d-ribose as the common chiral source. For the construction of 14 a bromobenzofuran derivative was used as a.
A stereoselective synthesis of the anti-ulcer compound AIB 1 is described. The 4-formylazetidinone 6 was converted into the 4-(Z)-alkene 23 using a phosphonate condensation, and dihydroxylation using osmium tetroxide and N-methylmorpholine N-oxide gave a mixture of the diols 24 and 25 in an 80∶20, protection of the diol 24 as its acetonide, hydrogenolysis gave the acid Stereoselective hydroxylation of the β-lactam ester is a key step in a total synthesis of by: Stereoselective total synthesis of AIB, a gastroprotective substance from Bacillus pumilus AI Yasumasa Hamada, Akiyoshi Kawai, Yasushi Kohno, Osamu Hara, and Takayuki Shioiri J.
Chem. Soc.,(4), pp – First total synthesis of AIB (1), a gastroprotective substance from Bacillus pumilus AI, was achieved in a stereoselective and convergent this synthesis, the dihydroisocoumarin part 2 was constructed in one step through 1,2-addition of the benzylic anion 17b to Boc-L-leucinal hydroxy amino acid 4 was elaborated from (R)-glutamic acid in a highly stereoselective by: Natural Products Total Synthesis and Biological Evaluation (62 total): Synthesis of biologically important natural products with anticancer, antibacterial, antiviral.

Synthesis of AIB ( The common amide intermediate amicoumacin C was then successfully converted further either into (−)-bacilosarcins A or B by a two-step sequence. In addition, they also reported another new efficient total synthesis of (−): Zhonglei Wang.
In book: Name Reactions and Reagents in Organic Synthesis, Second Edition, pp Total synthesis of AIB. A new stereoselective approach for the synthesis of AIB has been. The first total syntheses of izenamides A, B, and C, which are depsipeptides inhibitor of cathepsin D, were accomplished.
In addition, the stereochemistry of izenamide B was confirmed by our syntheses. The key features of our synthetic route involve the avoidance of critical 2,5-diketopiperazine (DKP) formation and the minimization of epimerization during the coupling of amino acids for the Author: Changjin Lim.

Classics in Total Synthesis II More Targets, Strategies, Methods This book was carefully produced. Nevertheless, editor, authors and ample, the steroid synthesis challenges proved instrumental in the develop-ment of the Diels–Alder reaction.
So too the synthesis challenges associated. 4-Acyl-β-lactams are important synthetic intermediates in both pharmaceutical and organic chemistry. Cis- and transacyl-β- lactams were synthesized stereoselectively from vicinal diketones via the formation of bulky and less bulky diimines as key intermediates, respectively.
The diimines reacted with acyl chloride in the presence of triethylamine to give Cited by: 3.
