available molybdenum(VI) oxides such as (NH4)2MoO4, (NH4)6Mo7O24·4H2O, MoO2(acac)2, and MoO2(TMHD)2 are highly effective dehydrative cyclization catalysts for the synthesis of a variety of oxazolines. The reaction proceeds with a complete retention of configuration at the β-position. For the dehydrative cyclization of cysteine derivatives, bis(2-ethyl-8-quinolinolato)dioxomolybdenum(VI) shows remarkable
(NH 4)2 MoO 4,(NH 4)6 Mo 7 O 24 ·4H 2 O,MoO 2(acac)2和MoO 2(TMHD)2等市售氧化钼(VI)是高效的脱水环化反应用于合成各种恶唑啉的催化剂。反应进行时将构型完全保留在β位。对于半胱氨酸衍生物的脱水环化反应,双(2-乙基-8-喹啉酮基)二氧钼(VI)显示出显着的催化活性,并在没有明显损失立体化学完整性的情况下提供了噻唑啉。C 2-外甲硫氨酸的位置。
