Yadav, Jhillu S.,Reddy, A. Srinivas,Reddy, Ch. Suresh,Reddy, Basi V. Subba,Saddanapu, Venkateshwarlu,Addlagatta, Anthony
experimental part, p. 696 - 706 (2011/04/16)
A highly stereoselective first total synthesis of amphidinin B is described. The key steps involved in this synthesis are the generation of the exo-double bond in the C1-C9 segment, the Barbier allylation, enzymatic kinetic resolutio
Synthesis of the southern FGHI ring system of azaspiracid-1 and investigation into the controlling elements of C28- and C36-ketalization
Zhou, Xiao-Ti,Lu, Liang,Furkert, Daniel P.,Wells, Charles E.,Carter, Rich G.
, p. 7622 - 7626 (2008/02/01)
Heading south: An efficient approach to the FGHI southern ring system of azaspiracid-1 is disclosed. Each of the eight stereogenic centers is generated with excellent diastereoselectivity. In addition, the stereochemical outcome of the ketalization steps could be controlled by careful selection of the conditions. Teoc = 2-(trimethylsilyl)ethoxycarbonyl; TMS = trimethylsilyl; TIPS = triisopropylsilyl; Bn = benzyl. (Chemical Equation Presented).
Silanediol inhibitors of angiotensin-converting enzyme. Synthesis and evaluation of four diastereomers of Phe[Si]Ala dipeptide analogues
Kim, Jaeseung,Hewitt, Gregory,Carroll, Patrick,Sieburth, Scott Mc. N.
, p. 5781 - 5789 (2007/10/03)
Four stereoisomers of a Phe-Ala silanediol dipeptide mimic have been evaluated as inhibitors of angiotensin-converting enzyme (ACE) and compared to ketone-based inhibitors reported by Almquist et al. One stereogenic center of the isomers was derived from
Silanediol peptidomimetics. Evaluation of four diastereomeric ACE inhibitors
Kim, Jaeseung,Sieburth, Scott McN.
, p. 2853 - 2856 (2007/10/03)
Four diastereomers of a Phe-Ala peptide mimic incorporating a central silanediol group have been individually prepared and tested as inhibitors of angiotensin-converting enzyme (ACE). Three of the silanediols exhibit levels of inhibition that are similar
Total Synthesis of (+)-Carbonolide B
Keck, Gary E.,Palani, Anandan,McHardy, Stanton F.
, p. 3113 - 3122 (2007/10/02)
The macrolide (+)-carbonolide B, the aglycon of the antibiotic carbomycin B, was synthesized via a convergent sequence.A key step of the approach is the union of aldehyde 6 with stannane 7 in the presence of MgBr2*OEt2 as Lewis acid to afford the C1-C9 fr
SYNTHESIS OF MOSESIN-4, A NATURALLY OCCURING STEROID SAPONIN WITH SHARK REPELLENT ACTIVITY, AND ITS ANALOG 7-β-GALACTOSYL ETHYL CHOLATE
Gargiulo, Dario,Blizzard, Timothy A.,Nakanishi, Koji
, p. 5423 - 5432 (2007/10/02)
The first synthesis of mosesin-4 (13), a naturally occurring steroid saponin with shark repellent activity, and its analog 19, is described.They both possess a free galactose residue attached axially at the 7α position of the steroidal aglycon.Methyl chol
