The utility of the unsaturated phosphonate 1 as a vinylogous Horner−Wadsworth−Emmons reagent was explored in reactions with aldehydes affording 4-methyldienoate esters. Factors that affect E/Z selectivity were studied. A simplified synthesis of trichostatic acid 3 was accomplished to demonstrate utility of this reagent.
在与提供4-甲基二烯酸酯的醛的反应中,探索了不饱和膦酸酯1作为乙烯基霍纳-沃兹沃斯-埃蒙斯试剂的用途。研究了影响E / Z选择性的因素。简化了三甲acid酸3的合成,以证明该试剂的实用性。
