An enantioselective Michael addition reaction of diphenylphosphine to substituted alkenylisoxazoles has been developed. The reaction proceeds efficiently under mild conditions with high yields (up to 99%) and moderate to excellent enantioselectivities (up to 92%) thus providing a hitherto unavailable direct access to a library of chiral tertiary phosphine‐functionalized isoxazoles.
已经开发了二苯基膦与取代的烯基异恶唑的对映选择性迈克尔加成反应。该反应可在温和的条件下高效进行,具有高收率(高达99%)和中等至出色的对映选择性(高达92%),从而提供了迄今为止无法直接访问的手性叔膦官能化异恶唑文库。
