The one-pot cyclization of 5-hexynoic acid to produce 3-alkoxy-2-cyclohexenones proceeds in good yields (58-90%). 3-Hexynoic acid was converted to its acyl chloride with the aid of oxalyl chloride and was cyclized to 3-chloro-2-cyclohexenone upon addition of indium(III) chloride. Subsequent addition of alcohol nucleophiles led to the desired 3-alkoxy-2-cyclohexenones.

shop. I am indebted for capable research assistance to Naomi Roht-Arriaza and Ellen Hertz. Ellen played a particularly vital role, providing conceptual enrichment, incisive intellect and warm nurturance throughout the finishing stages of this project. My special thanks go to James Tessier whose intellectual and personal contributions extend far beyond ordinary research assistance. Without Jim's...
The potency of oxalyl amino acid derivatives as inhibitors of prolyl 4-hydroxylase was studied in vitro, in isolated microsomes and in chicken embryonic-tissue culture. These compounds represent structural analogues of 2-oxoglutarate in which the -CH2- moiety at C-3 is replaced by -NH-, with or without further structural modifications. The most efficient inhibitor of purified prolyl 4-hydroxyla...
We studied hydrogen-bonding assemblies in a series of dumbbell-shaped hydrazine derivatives, namely oxalyl N',N'-bis(3,4-dialkoxybenzoyl)-hydrazide (BFH-n, n = 4, 6, 8, 10) and oxalyl N',N'-dibenzoyl-hydrazide (FH-0). It has been demonstrated that NH-1 protons of BFH-n precipitated from tetrahydrofuran (THF) or dimethylformamide (DMF) were involved in intramolecular H-bonding to form 6-membered...
