F. Hamzaoui et al., X-RAY STRUCTURE OF A NEW PYRETHROID, RU-52259, Acta crystallographica. Section C, Crystal structure communications, 49, 1993, pp. 818-820
The X-ray structure of this intermediate compound, tert-butyl pha-(ter
t-butylsulfonyl)-beta-(methoxysulfinyl)-3, phenoxybenzyl)oxycarbonyl]-
cyclopropanepropionate, shows the configuration of the asymmetric atom
s at sites C1, C2 and S1 (C(alpha)C(beta) and beta-S) and allows the m
echanism of its formation to be established. The bond distances in the
molecule are in the expected range.
