The first simple and efficient synthesis of the unusual dipeptide part of Phomopsin A
摘要:
A practical high yielding synthesis of the key halogenated dipeptide part of Phomopsin A 2 is reported. The key steps are a selective Heck coupling, a Sharpless asymmetric dihydroxylation in PEG and a benzoyl isocyanate mediated synthesis of dehydrovaline. (c) 2005 Elsevier Ltd. All rights reserved.

Radical-mediated acyl thiol-ene reactions between biologically relevant alkene and thioacid components enables rapid, chemoselective and high yielding thioester formation. This reaction in combination with substrates that enable intramolecular acyl transfer permits access to native and modified products beyond the thioether linkage.
This invention relates to compounds of Formula (I), (II), or (III) shown in the specification. These compounds can be used to treat hepatitis C virus infection.
A convenient synthesis of β,γ-unsaturated valine (l-3,4-didehydrovaline), an important constituent of an antibiotic phomopsin A, was achieved from H-D-Ser-OH through a seven-step conversion in 31% overall yield.
通过七步转化,以 H-D-Ser-OH 为原料,方便地合成了δ,δ³-不饱和缬氨酸(l-3,4-二脱氢缬氨酸),它是抗生素 phomopsin A 的一种重要成分,总收率为 31%。
