Abstract
Substituted isoxazoles are synthesized by dehydrogenation of the appro priate substituted isoxazolidines, prepared by 1,3-dipolar cycloadditi on of thiophene-2-carbaldehyde oxime with conventional dipolarophiles; based on these studies, cycloadducts obtained from 2-furaldehyde oxim e, previously reported as [4+2] adducts, are revised to 1,3-dipolar st ructures.
