The BINOL‐derived chiral phosphoric acid (R)‐TRIP is utilized as an organocatalyst in the asymmetric isoprenylboration reaction of aldehydes, wherein hydrogen‐bond interactions play a key role in the control of enantioselectivity. A wide arrays of enantioenriched dienyl homoallyl alcohols, including two natural products (−)‐Ipsdienol and (−)‐Ipsenol, have been successfully constituted. The synthetic
BINOL衍生的手性磷酸(R)-TRIP在醛的不对称异戊二烯硼化反应中用作有机催化剂,其中氢键相互作用在控制对映选择性中起关键作用。已经成功地构成了一系列丰富的对映体富集的二烯基均烯丙基醇,包括两种天然产物(-)-伊潘二醇和(-)-伊潘醇。还公开了对手性异戊烯基化的异苯并呋喃酮,乙烯基环氧乙烷和环己烯衍生物的合成应用。
