A time-dependent variant of the WKB method is developed for propagators which do not have the simple Feynman structure K = jexp(iS/h) with j = j( t). The method is applied to radial propagators for N-dimensional isotropic oscillators. An expansion in ascending powers of h results in an asymptotic se
