  Structure and synthesis of petrosynes, new acetylenic enol ether glycerides from the Okinawan marine sponge of the genus Petrosia

  摘要：

  Acetylenic enol ether glycerides, 1 and 3, were found in the Okinawan marine sponge of the genus Petrosia. The plane structures of these glycerides were deduced from spectroscopic analysis. Their complete structures were established by enantioselective total synthesis of all possible stereoisomers using (R)-1-O-benzylglycerol and its (S)-enantiomer, prepared from D-mannitol and L-ascorbic acid, respectively, as chiral building blocks. The synthesis involves the palladium(O)-catalyzed coupling reaction of bromo enol ether 9 with enediyne 21 as a key step. It became evident from the synthesis that the natural product 1 consisted of a mixture of (7R,2'S)-24 (petrosyne Ia) and (7S,2S)-24 (petrosyne Ib), and the natural product 3 consisted of a mixture of (7R,2'S)-28 (petrosyne IIa) and (7S,2'S)-28 (petrosyne IIb).

  natural phenolic homobenzyl esters, isolated from Phragmipedium calurum (an orchid) and Eupatorium fortunei TURCZ (a perennial herb in the Asteraceae family), respectively, were synthesized in enantiopure forms. By comparison of the optical rotations for the synthetic and the natural samples, the absolute configurations for the natural products were reliably assigned. The synthesis also enables establishment

  以对映纯的形式合成了两种最近鉴定出的天然酚类高苄基酯，分别从芦苇（兰花）和紫茎泽兰TURCZ（菊苣科的一种多年生草本植物）中分离出来。通过比较合成样品和天然样品的旋光度，可以可靠地指定天然产品的绝对构型。该合成还能够建立密切相关的天然高苄基醇的绝对构型，并首次提供了另外两种天然高纯苄基酯的完整的物理和光谱数据。
