A convenient strategy for the synthesis of β,γ-unsaturated aldehydes and acids. A construction of skipped dienes
摘要:
A novel strategy is described for the synthesis of beta,gamma-unsaturated aldehydes which are the useful synthons for the synthesis of arachidonic acid and other eicosanoid products. These beta,gamma-unsaturated aldehydes have been used in the total synthesis of arachidonic acid. (C) 1999 Elsevier Science Ltd. All rights reserved.

and 5,6-benzoarachidonic acid (3), potential substrate analogueinhibitors of leukotrienebiosynthesis, are described. Two of these compounds (1 and 2) apparently stimulated, while 3 inhibited, the activity of lipoxygenase from intact human polymorphonuclear leukocytes in vitro when stimulated with Ca2+ and calcium ionophore A23187 in the presence of BSA and arachidonicacid.

The synthesis of arachidonicacidderivativescontainingsite-specifically incorporated deuterium atoms and also a remotetritium label are described. Deuterium incorporation at the C11 and/or C15 position was achieved using Wittig chemistry, while the radiolabel was introduced at a remote position using [(3)H]NaBH(4) as the radiolabel source. These compounds can be used to measure secondary kinetic
The carba-analogs of 5-HPETE and leukotriene A4, unstable intermediates of slow-reacting substance (SRS), were synthesized. These carbaanalogs inhibited the 5-lipoxygenase. The carba-analog of leukotriene A4 was a particularly potent specific inhibitor of the 5-lipoxygenase.

The first total synthesis of a potent inflammatory mediator 5-oxo-6(E),8(Z), 11(Z),14(Z)-eicosatetraenoic acid (5-oxo-ETE) 2 and its biotransformation product 6,7-dihydro-5-oxo-ETE 5 is reported. A convergent synthesis for the unstable title compounds is accomplished via two synthons, dithiolane aldehyde 13 and bisdienyl phosphonium bromide 19. The synthetic 5-oxo-ETE 2 and its 8,9-trans isomer 3 were used to unequivocally confirm the structure of the biologically derived mediators. In addition, using synthetic 6,7-dihydro-5-oxo-ETE 5 we have been able to identify in neutrophils the formation of 6,7-dihydro-5-oxo-ETE 5.
