Drawing on field theory and social constructivism, the authors present a dynamic, cocreative approach to transactional analysis. This approach emphasizes the present-centered nature of the therapeutic relationship—or therapeutic relating—and the cocreative nature of transactions, scripts, ego states, and games. The authors frame this approach within a positive health perspective on transactional analysis (as distinct from an undue emphasis on psychopathology) and argue that cocreative transactional analysis provides a narrative or story about transactional analysis itself that offers new and contemporary meanings to old transactional truths. The article concludes with a series of questions for self-supervision that may serve as a useful guide to cocreative transactional analysis practice.
A smooth and conventional route to 5a.7a-cyclosteroids is described.THE solvolysis of the toluene-p-sulphonate of '' #cholesterol " (I; R = CH3C6H4S02) has been shown h2 to involve homoallylic interaction between the x-electrons of the 4,5-double bond and a carbonium ion at the 7-position, leading to 7p-substitution with retention of configuration, and cholest-4,6-diene (11) by elimination. Kinetic studies of the acetolysis of cholest-4-en-7p-yl tolune e-p-sulphonate (I ; R = CH,C6H,S02) confirm the conclusion of Shoppee et aZ.l * For nomenclature see ref. 7.
The i-steroid rearrangement is shown to involve inversion of configuration a t C(3) and to yield 6P-substituted derivatives of 3 : 5-cyclosteroids. A 6a-substituted 3 : 5-cyclosteroid has been prepared indirectly. The rearrangement exhibits some analogies with Wagner substitution and a mechanism for the change is suggested and discussed. THE i-steroid rearrangement is a general reaction whereby derivatives of 3p-hydroxy-A5-steroids afford 6-substituted 3 : 5-cyclosteroids. Thus methanolysis of cholesteryl toluene-+-sulphonate or chloride gives cholesteryl methyl ether, m. p. 84O, [a]= -46O, but in the presence of potassium acetate furnishes i-cholestanyl methyl ether (6-methoxy-3 : 5-cycZocholestane), m. p. 79", [a]= +55" (Stoll, 2. +hysioZ. Chem., 1932, 207, 147; 15, 74) ; and chlorination of methylcyclopropane gives a mixture containing approximately equal quantities of cyclopropylmethyl chloride and but-3-enyl chloride (Roberts and Mazur,
4P-Methoxycholest-5-ene and 6B-methoxycholest-4-ene have been prepared and shown to be identical with the products isolated from the methanolysis of epicholesteryl toluene-p-sulphoAate by Evans and Shoppee (J., 1953, 540).Hydrogenation of cholest-5-en-4P-01, its acetate, and its methyl ether gave by hydrogenolysis only cholestane, whereas hydrogenation of cholest-5-en-4a-01 gave cholestan-4a-01. Hydrogenation of the epimeric Gacetoxyand 6-hydroxycholest-4-enes gave respectively the epimeric Gacetoxycoprostanes or the epimeric coprostan-6-01s ; the latter by cautious oxidation both yielded coprostan-6-one, isomerised by acid, alkali, or alkaline aluminium oxide to cholestan-&one.Reduction of 5-hydroxycholestan-4-one with sodium-n-propanol gave the expected products, cholestan-4a-01 and cholestane-4% : 5-diol; similar reduction of 5-hydroxycholestan-6-one gave cholestan-6a-01, and cholestane-5 : 6adiol accompanied by coprostane-5 : 6a-diol.t Since this paper was submitted, the partial svntheses of the methyl ethers (V) and (VI) and of related compounds have been described by Bccker i n d Wallis (
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
