    摘要: This invention relates to 2-(substituted)-N-hydroxy-N-alkylcinnamamides of the formula: ##STR1## where R.sup.1 is C.sub.1 -C.sub.4 alkyl;n is 0 or 1;R.sup.2 is trifuloromethyl, C.sub.1 -C.sub.10 alkyl, phen(C.sub.1 -C.sub.4)alkylene or ##STR2## where m is 0, 1 or 2 and R.sup.3 is C.sub.1 -C.sub.4 alkyl; X is C.sub.1 -C.sub.6 alkyl, phenyl, phen(C.sub.1 -C.sub.4)alkylene where the phenyl ring is unsubstituted or monosubstituted with --S(O).sub.m --R.sup.3 and m and R.sup.3 are as defined above, or ##STR3## where m is 0, 1 or 2 and R.sup.4 is C.sub.2 -C.sub.12 alkenyl, C.sub.2 -C.sub.12 alkynyl, or unsubstituted or monosubstituted C.sub.1 -C.sub.20 alkyl where the substituent is CF.sub.3, C.sub.3 -C.sub.8 cycloalkyl, or phenyl,or a pharmaceutically acceptable salt thereof; formulations containing those compounds and methods of using such compounds as 5-lipoxygenase inhibiting agents.

    摘要: A novel process for the oxidation of olefins to the corresponding alpha-epoxy alcohols which can be incorporated in the total synthesis of members of a novel class of prostaglandin analogues.Olefins are reacted with singlet oxygen in the presence of a group IVB, VB or VIB transition metal catalyst, excluding chromium. The reaction is fast and highly selective to the alpha-epoxy alcohol. When cyclopentene is oxidized in the process of the invention, high yields of cis 2,3-epoxy-cyclopentan-1-ol are obtained. The latter compound is used as a starting material in the synthesis of prostaglandin analogues. The prostanoids of the invention are characterized by an oxa group replacing the methylene group at the 7-position, and the absence of a hydroxyl or other substituent at the 11-position.Members of this class of prostanoids show important cytoprotective properties in animal tests.
