摘要

The naturally occurring 1, 4-benzoquinones 2-methoxy-6-propyl-1, 4-benzoquinone (1), 2- methoxy-6-pentyl-1, 4-benzoquinone (primin 2), 2-methoxy-6-pentadecyl-1, 4- benzoquinone (3), 2-methoxy-6-heptadecyl-1, 4-benzoquinone (dihydroirisquinone, pallasone B; 4) were synthesized by a simple protocol involving microwave accelerated Claisen rearrangement of allyl ethers 10, followed by hydrogenation of the side chain ...
