Health services and medical social work are being reshaped in the wake of managed care and the movement toward community-based delivery systems. In this article, a bachelor's of social work student is assigned to a field placement to work with a hospital-owned physician practice in a skilled nursing facility. Structured interviews are conducted with the field placement student, the physician, a resident (client), the field placement instructor, two social work designees, and the facility administrator to ascertain the student's practice activities. Findings indicate a wide range of duties at both micro- and macro practice levels. Value issues and potential considerations for practitioners entertaining professional associations with physicians are examined.

The synthesis of N-tosylated and N-Boc-protected 2-hydroxymethyl-pyrroles 2a-c and 3a-d and their transformation into di- and tripyrroles 18, 20a and 20b as well as the preparation of the vinyl- and ethynylpyrroles 13a, 13b and 15 is described. The pyrrole-2-carboxylic acid ethyl esters 7a and b and the pyrrole-2-carbaldehydes 4a-d were transformed into their N-protected derivatives 5a, 5b, 6a-d, 8a and 8b in 69-97% yield and reduced to give the corresponding hydroxymethylpyrroles 2a-c and 3a-d in 79-96% yield; treatment of 2b with 17, 19a and 19b in 0.5% hydrochloric acid gives the dipyrrole 18 and the tripyrroles 20a and 20b in 20-28% yield.

synthesis and characterization, including the stereochemistry, of a series of 3,4-dihydropyrromethenones and 2,3-dihydrodioxobilins are described. High-resolution /sup 1/H NMR spectral analysis allows the determination of the A ring coupling constants for a series of cis and trans model compounds. From these data and correlations, the relativestereochemistry in the A ring of phycocyanin and similar bile
描述了一系列 3,4-dihydropyrromethenones 和 2,3-dihydrodioxobilins 的合成和表征,包括立体化学。高分辨率 /sup 1/H NMR 光谱分析允许确定一系列顺式和反式模型化合物的 A 环耦合常数。根据这些数据和相关性,可以得出藻蓝蛋白 A 环中的相对立体化学和类似胆色素结构的结论。
