  Development of a Titanocene-Catalyzed Enyne Cyclization/Isocyanide Insertion Reaction

  摘要：

  The first early transition metal-catalyzed enyne cyclization reaction is described. The system converts enyne substrates to bicyclic iminocyclopentenes through the use of 10 mol % of Cp(2)Ti(PMe(3))(2) in the presence of a silyl cyanide. Subsequent hydrolysis produces the corresponding bicyclic cyclopentenones in good overall yield. The cyclization reaction is tolerant of polar functional groups such as ethers, amines, and esters and is diastereoselective with certain chiral enyne substrates.

  between propargylic phosphates and aryl- or alkenylboronates afforded aryl- or alkenyl-conjugated allenes. The reaction showed excellent functional group compatibility in both the propargylic substrates and the boronates. The reaction of an enantioenriched propargylic phosphate proceeded with excellent chirality transfer with 1,3-anti stereochemistry to give axially chiral aryl- and alkenylallenes.

  aldehydes are used to prepare the propargylic alcohol-based chiral en-ynes. Protection of the propargylic alcohols with either an acetyl or a methyl group allows the resulting en-ynes to undergo the intramolecular Pauson−Khand reaction to form the corresponding optically active 5,5- and 5,6-fused bicyclic products with high diastereoselectivity and high enantiomeric purity. In the major product, the propargylic

  用于将醛催化不对称炔烃加成醛的几种方法用于制备基于炔丙醇的手性烯炔。用乙酰基或甲基保护炔丙醇可以使所产生的烯炔分子内发生Pauson-Khand反应，形成具有高非对映选择性和高非对映活性的5,5-和5,6-稠合双环产物对映体纯度。在主要产物中，炔丙基取代基和桥头氢在稠合双环上相对于彼此是顺式的。由不对称炔烃加成产生的炔丙醇的对映体纯度在环加成产物中得以保持。制备手性炔丙醇的烯丙基醚，其还可以进行高度非对映选择性的Pauson-Khand环加成，并保留高对映体纯度。这项研究表明，炔丙基位置以及炔烃上取代基的大小对于非对映选择性很重要，取代基的体积越大，非对映选择性就越高。

  [GRAPHICS]Additions of terminal alkynes to electrophiles are important transformations in organic chemistry. Generally, activated terminal alkynes react with epoxides in an S(N)2 fashion to form homopropargylic alcohols. We have developed a new synthetic method to form propargylic alcohols from epoxides and terminal alkynes via 1,2-shifts. This method involves cationic zirconium acetylides as both the activator of epoxides and nucleophiles. line to the mild conditions to pre-activate alkynes with silver nitrate, this synthetic method is useful for both electron-rich and electron-deficient alkynes with other acid- and base-sensitive functional groups.
