efficient 2 aryl benzothiazole formation from aryl ketones and 2 aminobenzenethiols under metal free conditions
Organic Letters, 2012Co-Authors: Yunfeng Liao, Shanping Chen, Pengcheng Jiang, Wang Zhou, Guojun DengAbstract:2-Aryl benzothiazole formation from aryl ketones and 2-aminobenzenethiols under metal- and I(2)-free conditions was described. Various 2-aryl benzothiazoles were selectively obtained in good yields using molecular oxygen as oxidant. DMSO played an important role in this transformation. Functional groups such as methyl, methoxy, fluoro, chloro, bromo and nitro groups were tolerated under the optimized reaction conditions.

Validation of telephone administration of 2 condition-specific quality-of-life questionnaires
American Journal of Obstetrics and Gynecology, 2007Co-Authors: Elizabeth J Geller, Elizabeth R Barbee, Mary J Loomis, Anthony G ViscoAbstract:Objective To validate telephone-administered versions of 2 condition-specific quality of life questionnaires: Pelvic Floor Distress Inventory and Pelvic Floor Impact Questionnaire. Study Design Between December 2005 and September 2006, 55 women were recruited at their 6-week postpartum visit at a university hospital. Written and telephone versions of the 2 questionnaires were completed, with a 2-week interval between each version. The order of administration was randomized. Results The scores of the written vs telephone versions of the questionnaires were not significantly different (PFDI: 9.8 vs 9.0 respectively; P = .36; PFIQ: 4.4 vs 3.7 respectively; P = .38). These scores were also highly correlated (PFDI, r=0.96 and PFIQ, r=0.90). Conclusion Telephone administration of these instruments is a reliable and accurate measure of the impact of pelvic floor disorders and may facilitate clinical and epidemiologic research by decreasing cost and improving access to research participants.
