在这里,我们描述了我们的全面研究的细节,这些研究导致了总的纳米囊藻毒素Ax的合成,这是一种由三肽片段和聚酮化合物片段组成的21元大环天然产物,其特征在于8个最长的线性步骤中的特征为13.9%总总产量。关键的合成策略依靠后期的斯蒂勒偶联进行大环内酯化,以构建21元环,而三肽片段和聚酮化合物片段之间的直接连接失败。1 H NMR实验表明,nannocystin Ax应该在氘代溶剂中以构象混合物形式存在。
LIPASE-CATALYZED RESOLUTION OF 4-TRIMETHYLSILYL-3-BUTYN-2-OL AND CONVERSION OF THE (R)-ENANTIOMER TO (R)-3-BUTYN-2-YL MESYLATE AND (P)-1-TRIBUTYLSTANNYL-1,2-BUTADIENE
Synthesis of Stereopentad Analogues of the C14−C22 Segment of Callystatin A through Additions of Chiral Allenylzinc Reagents to Stereotriads

日期:2001.11.1
The addition of (P)- and (M)-allenylzinc reagents, prepared in situ through Pd-catalyzed metalation of (R)- and (S)-3-butyn-2-ol mesylates, to diastereomeric stereotriad aldehydes 8, 13, 18, and 23 of syn,syn, syn,anti, anti,anti, and anti,syn stereochemistry was examined. Additions to the former two aldehydes afforded the four anti adducts with high diastereoselectivity and negligible mismatching

A highly stereoselectivesynthesis of a model C(18)–C(35) spiroketal unit (7) of integramycin has been accomplished via an enantioselective stannyl-crotylboration reaction and an N-iodosuccinimide-mediated spiroketalization of 19a.

日期:2012.11.2
The totalsynthesis of FD-895 was completed through a strategy that featured the use of a tandem esterification ring-closing metathesis (RCM) process to construct the 12-membered macrolide and a modified Stille coupling to append the side chain. These studies combined with detailed analysis of all four possible C16–C17 stereoisomers were used to confirm the structure of FD-895 and identify an analog
