File:Bay.gif

Poor quality (badGIF), not used, replaced by File:Bay.svg. Leyo 14:41, 21 November 2011 (UTC)[reply]

Delete per nom. However, both original and the replacement have a stereochemical problem because it has a wedge between two stereocenters (see annotation on the svg image). According to scifinder, the chemical "Bay 60-7550" has an imidazole ring, not the dihydroimidazole in these diagrams. A C=N double bond would give a structure without geometric confusion (since the C in the ring would not be a stereocenter). DMacks (talk) 22:42, 22 November 2011 (UTC)[reply]
Comment - I drew the replacement svg, based on the gif. I've just tried Reaxys and it gives

2-(3,4-dimethoxybenzyl)-7-{(1R)-1-[(1R)-1-hydroxyethyl]-4-phenylbutyl}-5-methylimidazo[5,1-f][1,2,4]triazin-4(3H)-one

Bay 60-7550

And it is an imidazole ring - I'll go and fix the svg. Ronhjones ^(Talk) 01:11, 23 November 2011 (UTC)[reply]

Looks good. I stand by my "kill the old", now with no reservations. DMacks (talk) 02:19, 23 November 2011 (UTC)[reply]

But what about the old stereo center (wedge)? --Yikrazuul (talk) 20:46, 23 November 2011 (UTC)[reply]

The change made one of the two atoms on it sp², so now the wedge is only connected to one tetrahedral center. I think ACS/IUPAC recommend against using any end of a stereo bond on a planar position, but I often see nucleic-acid structures use wedge/dot for the aromatic substituent on a chiral center. It seems to be completely clear here what the meaning is (unlike before)? DMacks (talk) 12:19, 26 November 2011 (UTC)[reply]
