A product of p-tert-butylphenyl propionaldehyde and m-tert-butylphenyl propionaldehyde, wherein m-tert-butylphenyl propionaldehyde is in an amount from 6% to 60% of the combination of p-tert-butylphenyl propionaldehyde and m-tert-butylphenyl propionaldehyde. Also a method including; adding dropwise an aldehyde solution to a basic solution; and, collecting a fraction of p-tert-butyl cinnamic aldehyde m-tert-butyl cinnamic aldehyde therefrom; and, adding a transition metal catalyst to a solution of the p-tert-butyl cinnamic aldehyde in ethanol, and, collecting therefrom by distillation a product of p-tert-butylphenyl propionaldehyde and the meta isomer m-tert-butylphenyl propionaldehyde; wherein the product comprises m-tert-butylphenyl propionaldehyde in an amount from 6% to 60% of the combination of p-tert-butylphenyl propionaldehyde and m-tert-butylphenyl propionaldehyde.

The vanilloid receptor-1 (TRPV1 or VR1) is a member of the transient receptor potential (TRP) family of ion channels and plays a role in regulating the function of sensory nerves. A growing body of evidence demonstrates the therapeutic potential of TRPV1 modulators, particularly in the management of pain. As a result of our screening efforts, we identified (E)-3-(4-tert- butylphenyl)-N-(2,3-dihydrobenzo[b][1,4]dioxin-6-yl)acrylamide (1), an antagonist that blocks the capsaicin-induced and pH-induced uptake of 45Ca2+ in TRPV1-expressing Chinese hamster ovary cells with IC50 values of 17 ± 5 and 150 ± 80 nM, respectively. In this report, we describe the synthesis and structure-activity relationship of a series of N-aryl cinnamides, the most potent of which (49a and 49b) exhibit good oral bioavailability in rats (Foral = 39% and 17%, respectively).

The addition of organolithium reagents to the oxa tricyclic ketone 1 occurs stereospecifically to produce the corresponding tertiary carbinols 2a-d.When the alcohols 2a-d are treated with TiCl4, ring fragmentation and dehydration occur to produce good yields of 5,6-dihydrobenzaldehydes 3a-d.Oxidation of aldehydes 3a-d then leads to the corresponding meta-substituted benzaldehydes 4a-d.Alternatively, use of the Lewis acid Me2BBr did not stop at the dihydrobenzaldehyde stage.Tautomerization of the diene aldehydes 3a-d produced meta-substituted benzyl alcohols 7a-d or benzyl bromides 8a-d under prolonged reaction times.The addition of silica gel to the reactions accelerated the formation of the benzyl bromides.
