Leukotriene biosynthesis inhibitors have potential as new therapies for asthma and inflammatory diseases. The recently disclosed thiopyrano[2,3,4- cd]indole class of 5-lipoxygenase (5-LO) inhibitors has been investigated with particular emphasis on the side chain bearing the acidic functionality. The SAR studies have shown that the inclusion of a heteroatom (O or S) in conjunction with an alpha-ethyl substituted acid leads to inhibitors of improved potency. The most potent inhibitor prepared contains a 2-ethoxybutanoic acid side chain. This compound, 14d (2-[2-[1-(4-chlorobenzyl)-4-methyl-6-[(5- phenylpyridin-2-yl)methoxy]-4,5-dihydro-1H-thiopyrano[2,3,4-cd]indol-2- yl]ethoxy]butanoic acid, L-699,333), inhibits 5-HPETE production by human 5- LO and LTB4 biosynthesis by human PMN leukocytes and human whole blood (IC50s of 22 nM, 7 nM and 3.8 muM, respectively). The racemic acid 14d has been shown to be functionally active in a rat pleurisy model (inhibition of LTB4, ED50 = 0.65 mg/kg, 6 h pretreatment) and in the hyperreactive rat model of antigen-induced dyspnea (50% inhibition at 2 and 4 h pretreatment; 0.5 mg/kg po). In addition, 14d shows excellent functional activity against antigen-induced bronchoconstriction in the conscious squirrel monkey [89% inhibition of the increase in R(L) and 68% inhibition in the decrease in C(dyn) (0.1 mg/kg, n = 3)] and in the conscious sheep models of asthma (iv infusion at 2.5 mug/kg/min). Acid 14d is highly selective as an inhibitor of 5-LO activity when compared to the inhibition of human 15-LO, porcine 12-LO and ram seminal vesicle cyclooxygenase (IC50 > 5 muM) or competition in a FLAP binding assay (IC50 > 10 muM). Resolution of 14d affords 14g, the most potent diastereomer, which inhibits the 5-HPETE production of human 5-LO and LTB4 biosynthesis of human PMN leukocytes and human whole blood with IC50s of 8 nM, 4 nM, and 1 muM respectively. The in vitro and in vivo profile of 14d is comparable to that of MK-0591, which has showed biochemical efficacy in inhibiting ex vivo LTB4 biosynthesis and urinary LTE4 excretion in clinical trials.

A modular stereoselective synthesis of the vesicular monoamine transport inhibitors (+)-tetrabenazine ((+)-1) and (+)-alpha-dihydrotetrabenazine ((+)-2) has been developed. The approach is based on amine 4 and acid 5 as the key building blocks, which were elaborated into macrolactam 3 by amide coupling and a subsequent highly E-selective RCM reaction. Macrolactam 3 could be converted into tetrabenazine in three known steps.

Chiral N-(diethoxymethyl)oxazolidinones, prepared from the corresponding oxazolidinones by heating in trielhyl orthoformate, can be used as organozinc carbenoid precursors for the direct enantioselective amidocyclopropanation of alkenes. The reaction is successful with a wide range of oxazolidinones and alkenes and proceeds with moderate to excellent yield and stereoselectivity. In most cases the trans/exo amidocyclopropane product, is favoured, although certain cyclic alkenes such as indene favour the formation of the endo cyclopropane. The products can be readily elaborated to produce cyclopropylamino alcohols and amino acids. Wiley-VCH Verlag GmbH & Co. KGaA.

The reaction of beta-amino alcohols with 1,1?carbonyldiimidazole in dichloromethane is affected by the size of the nitrogen substituent. 1,3-Oxazolidin-2-ones are exclusively obtained from N-H, N-methyl and N-arylmethyl derivatives. O-(1-Imidazolyl)carbonyl derivatives are formed as intermediates from N-[1-(2-pyridyl)alkyl]-(S)-valinol and are mainly or exclusively converted into aziridines in the presence of water, although the cyclization is impeded by large N-substituents such as triphenylmethyl.

In response to a recent literature report by Decicco and Leathers, the work of Hale, Delisser, and Manaviazar (1992) on the asymmetric synthesis of (3R)- and (3S)-piperazic acids has been reinvestigated, and the originally claimed product yields fully substantiated. The claims made in reference 13 about the proportions of cyclised product 6 and starting bromide 20 isolated from the low temperature electrophilic hydrazination-nucleophilic cyclisation of 20 with di-t-butylazodicarboxylate (DBAD) and DMPU as an additive are inaccurate. The retro-hydrazination reaction that they claim is problematic when DMPU is added to the hydrazinated reaction mixture has been demonstrated not to have a seriously detrimental effect on cyclisation product yield and to be unimportant. The other main ion of reference 13, that the electrophilic hydrazination and nucleophilic cyclisation of 20 gives 6 in 91% isolated yield when n-Bu4NI is employed as an additive (instead of DMPU) has also been shown to be in error. We have carefully repeated a scaled-down version of the n-Bu4NI catalysed procedure and have found that 6 is generally isolated in yields of 50-56% after flash chromatography. We have concluded that n-Bu4NI does not significantly increase the yields of cyclisation products 6 or 17 when it is employed as a cyclisation additive. Herein, we report details of our two preferred ‘crude’ experimental procedures for preparing the enantiomers of piperazic acid in high optical purity, neither of which requires chromatographic purification of the reaction intermediates en route. Both these preferred ‘crude’ methods for preparing 11 and 19 have been consistently reproduced many times in these laboratories over the past few years. In our view, they remain the most expedient and highest yielding methods currently available for obtaining 11 and 19 in high optical purity.

I am very proud of our efforts over the past few months and hope to 16251-45-9 help many people in the next few years. Computed Properties of C10H11NO2
