Prins and olefin cross-metathesis reactions were used as the key steps for the stereoselective total synthesis of (+)-strictifolione and (6R)-6-[(4R,6R)-4,6-dihydroxy-10-phenyldec-1-enyl]-5,6-dihydro-2H-pyran-2-one. Removal of MOM protecting groups under neutral conditions using CeCl3·7H2O is an attractive addition to the present strategy.
Prins和烯烃的交叉复分解反应被用作(+)-strictifolione和(6 R)-6-[(4 R,6 R)-
4,6-二羟基-10-苯基
癸酸酯的立体选择性全合成的关键步骤-1-烯基] -5,6-二氢-2 H-
吡喃-2-一。使用CeCl 3 ·7H 2 O在中性条件下去除MOM保护基是本策略的一项有吸引力的补充。
