The acylzirconocene chloride complex as an acyl group donor reacts with omega-unsaturated alpha,beta-enones and -ynones under Pd-Me(2)Zn(Me(2)AlCl)-catalyzed conditions to give stereoselectively bicyclo[3.3.0] compounds through (i) formation of a Pd(II) intermediate by an oxidative addition of the Pd(0) catalyst to an enone function, (ii) cyclization of the(More)
In a morbidly obese parturient, epidural anesthesia is occasionally difficult because of great distance from the skin to the epidural space, and difficulty in identification of appropriate landmarks.
