challenging to synthesis. In addition, these compounds are typically unstable, rendering the separation difficult. We report herein a practical and concise route to a new class of stable, easy-separable allenyl B(MIDA) via a hydrazination/fragmentation of B(MIDA)-propargylic alcohols. The synthesis of optically active allenyl B(MIDA) was also achieved. Interesting reactivity of the resulting product was
Allenylboronates 代表了一类非常有趣的有机硼,但合成具有挑战性。此外,这些化合物通常不稳定,使分离变得困难。我们在此报告了一种通过B(MIDA)-炔丙醇的肼化/碎片化获得一类新的稳定、易于分离的丙二烯基 B(MIDA) 的实用且简洁的途径。还实现了光学活性丙二烯基B(MIDA)的合成。观察到所得产物的有趣反应性。
