    A More Comprehensive and Highly Practical Solution to Enantioselective Aldehyde Crotylation
    摘要:
    The enantioselective crotylation of aldehydes with 1,2-diaminochlorocrotylsilane reagents is effectively catalyzed by Sc(OTf)(3). The one significant limitation on the utility of these reagents - substrate scope - has thus been addressed. The net result is the most comprehensive and highly practical method for enantioselective aldehyde crotylation yet advanced.

  • A Highly Stereoselective, Efficient, and Scalable Synthesis of the C(1)–C(9) Fragment of the Epothilones
    作者:Corinne N. Foley、James L. Leighton
    DOI:10.1021/acs.orglett.5b03034
    日期:2015.12.4
    second-generation synthesis of the C(1)–C(9) fragment of the epothilones is reported. The key tandem intramolecular silylformylation/crotylsilylation/“aprotic” Tamao oxidation sequence has been redeveloped as a stepwise intermolecular variant, allowing excellent levels of diastereoselectivity in the crotylation step and proceeds in 50% overall yield on gram scale. An improved synthesis of the homopropargyl

  • Tandem Silylformylation−Crotylsilylation/Tamao Oxidation of Internal Alkynes: A Remarkable Example of Generating Complexity from Simplicity
    作者:Jared T. Spletstoser、Michael J. Zacuto、James L. Leighton
    DOI:10.1021/ol802489w
    日期:2008.12.18
    The rhodium-catalyzed tandem silylformylation-crotylsilylation reaction has been extended to include internal alkynes. Tamao oxidation of the initial product leads to the production of a substituted enol, which undergoes highly diastereoselective tautomerization. The resulting one-pot procedure fashions three new stereocenters, a ketone, and a terminal alkene from a butenyl group, a propynyl group
