The first synthesis of 1-(3'-methoxypropanoyl)-2,4,5-trimethoxybenzene 4, a natural phenylpropanoid occurring in Cordia alliodora, has been achieved, from β-asarone 1 of Acorus calamus. Selenium dioxide oxidation of 1 leads to 2,4,5-trimethoxycinnamaldehyde 2, which on treatment with sodium cyanide, acetic acid, manganese dioxide in methanol yields methyl 2,4,5-trimethoxycinnamate 3. Selective reduction of 3 gives 4 as a solid, spectral data of which agrees well with reported natural viscous gum 4.

Phloroglucin (or called phloroglucinol) is 1,3,5-trihydroxybenzene which presents as the genin of many glycosides, particulrally in the bark of apple and other trees.

Intramolecular copper(I)-catalyzed 2π + 2π photocycloaddition was exploited as the key step for generating the bicyclo[3.2.0]heptane portion of 2a from the 1,6-heptadiene 16, which was assembled from 1,3,5-trimethoxybenzene in six steps.

It is nonspecific with respect to base or sugar moieties of nucleotides. A variety of synthetic substrates are hydrolyzed. See review by Razell (1963). Ogilvie and Hruska (1976) indicate that exonuclease will not recognize nucleoside units in the syn conformation. See also Philipps and Chiemprasert (1975).
