The fraws-cinnamic acids are found to crystallize in three types of crystal structure corresponding to each type here there is a specific photochemical behavior. One type, designated p, has adjacent molecules translationally related by a short crystal axis of 4.0 A materials of this type react photochemically to give mirror-symmetric cyclobutanes (j3-truxinic acids) (Scheme 1). 

Similar nonalkaloidal classes of compounds were isolated from Nuphar lutea thus, the presence of fraws-cinnamic, arachidic, behenic, and palmitic acids was confirmed in rhizomes (27) and that of ellagic, caffeic, p-coumaric, sinapic, and... 

Cabaleiro and Johnson (1967) report that the addition of chlorine to -methyl cinnamate in chloroform or acetic acid is syn-selective, SS 0-75, in chloroform and acetic acid acetoxychloro derivatives are produced as well. Again, Dewar and Fahey (1964) argue that the normal course of addition of hydrogen halides onto olefins is a polar electrophilic process involving classical carbonium ions as intermediates and leading mostly but not exclusively to cis-adducts. A syn-preference was found in the additions of deuterium bromide to acenaphthylene, indene, and cis- and fraws-phenylpropene. In the case of indene, phenylpropene and methyl cinnamate, which are styrene analogs, concerted syn addition is symmetry-allowed (see bottom of p. 273).
