The reactions of any individual member of the series are conditioned by two factors: the nature of the alcoholic hydroxyl group, which may be primary, secondary, or tertiary, and the relative positions of the functional by: 1. Malic acid is an organic compound with the molecular formula C 4 H 6 O is a dicarboxylic acid that is made by all living organisms, contributes to the sour taste of fruits, and is used as a food acid has two stereoisomeric forms (L- and D-enantiomers), though only the L-isomer exists salts and esters of malic acid are known as al formula: C₄H₆O₅.

present in acids, such as acetyl CH3 — C —, leads to the f orma-II tion of acids (acetic acid CH3 — C — OH). The alcohols show their basic character by reacting with acids form water and substances which show some resemblance to salts.

These compounds are known as ethereal salts or esters. to The. additions with substituted 3,4-dihydronaphthoic acids led to analogous hexahydrophenanthrene~carboxylic acids'26 In general the yield of addition products from acids is superior to that from their esters (Table III), and, except where the acids cause polymerization of the diene 26 or the acids are unstable to heat, the esters have.

The present invention describes methods and compositions for improving the therapeutic efficacy of therapeutic agents previously limited by suboptimal therapeutic performance by either improving efficacy as monotherapy or reducing side effects. Such methods and compositions are particularly applicable to bisantrene or derivatives, analogs, or prodrugs thereof.

The facile dissociation of isobenzofuran and isobenzothiophene ad-ducts is remarkable because such dissociation must disturb an aromatic structure.

The dibasic acid formed from acetone dicarboxylic acid must have its carboxyls adjacent to the hydro xyl with the nitro group in the para place. Through the action of fuming nitric acid it was converted, as is also the {a) w-nitrosalicyilic acid, into picric acid (2, 4, 6-trinitrophenol.).

They made it evident that even in the case of the salts of these acids it is necessary to assume that, in the reaction with water, the final stage must be preceded by a dissociation of the salt into an isocyanate and a potassium salt of the acid related to the acyl group which had replaced the hydrogen of the oxime group: R.C(OK): NOCOR' = R.N.
