    日期:2002.6
    Treatment of ketene with α,β-unsaturated aldehydes and ketones in the presence of [Pd(dppb)(PhCN)2](BF4)2 leads to the formation of 4-vinyloxetan-2-ones, which rearrange under the conditions to give 3,6-dihydro-2H-pyran-2-ones in a variety of yields, depending on the substituents. Asymmetric induction with up to 57% de has been achieved by using α,β-unsaturated aldehydes bearing an asymmetric carbon
    在[Pd(dppb)(PhCN)2 ](BF 4)2存在下,用α,β-不饱和醛和酮处理乙烯酮会导致形成4-乙烯基氧杂环丁烷-2-酮,并在以下条件下重排:取决于取代基,以各种收率得到3,6-二氢-2 H-吡喃-2-酮。通过使用在β位置带有不对称碳中心的α,β-不饱和醛,可以实现高达57%de的不对称诱导。通过对4-乙烯基氧杂环丁烷-2-酮的C(4)-O键进行异质裂解而产生的两性离子被认为是烯丙基重排的中间产物。3,6-二氢-6-甲基-2 H的乙醇分解-吡喃-2-酮在酸性条件下,然后将所得的2,4-己二烯酸乙酯(山梨酸乙酯)皂化,以90%的产率得到山梨酸。

    Described herein polymer precursor compounds (aka polymer building blocks) of derived from biobased compounds, and specifically biobased mevalonolactone and its related derivatives. Through oxidation these biobased precursors can be reacted to yield building blocks for (unsaturated-) polyesters, polyester polyols and polyamides, as well as precursors for glycidyl esters and omega-alkenyl esters. Through reduction, these biobased precursors can be reacted to yield building blocks for (unsaturated-) polyesters, polyester polyols, polycarbonates, as well as precursors for glycidyl ethers and omega-alkenyl ethers. Through nucleophilic ring opening and/or amidation, these biobased precursors can be reacted to yield building blocks for polyester polyols, chain-extender for polyurethanes, or polyester-amides.

  • Intramolecular additions of allylsilanes to conjugated dienones
    作者:George Majetich、Kenneth Hull
    DOI:10.1016/s0040-4020(01)87742-5
    日期:1987.1
    Two stereospecific total syntheses of -widdrol () are reported. The first synthesis features the cyclization of dienone to construct bicyclic adduct which is converted to -widdrol using conventional procedures. A second synthesis exploits the cyclization of dienone 17 to prepare functionalized bicyclo[5.4.0]undecene , which is converted to a known -widdrol precursor.
    报告了-widdrol()的两种立体有择的合成方法。第一次合成的特征是将二烯酮环化以构建双环加合物,然后使用常规方法将其转化为-widdrol。第二种合成方法是利用二烯酮17的环化反应制备官能化的双环[5.4.0]十一碳烯,然后将其转化为已知的-widdrol前体。
