What were the reactions of early Jewish leaders to claims that Jesus had risen from the grave? Did they issue any refutations?

No, there are no reactions recorded.

In general there isn't a whole lot of written material about Christianity from Jewish sources in this period. Rabbinic sources do have occasional reference to Jesus, but they don't generally contain meaningful details. It's also an issue that the narratives put Jesus in the wrong time period. It is likely that they are literary ways to talk about Christianity in general, but because of distance from the context of authorship (and the massive amount of censorship that's happened of these passages) the exact meaning is not entirely clear.

None of these have any reference to a resurrection at all, much less any refutation of it. Really, the period was a very tumultuous time for Judaism in general, and most Rabbinic texts are intended for internal consumption. So it is somewhat unlikely that opinions on Christianity would be discussed very much.

The big exception to all this is Josephus, who was Jewish and wrote history texts. He did not refute Jesus's supposed resurrection, he actually records it as a historical event. But that passage is likely to have been either tampered with or entirely added by Christian scribes, since it would be somewhat incongruous for a Jewish author to write that, even at such an early time before Christianity and Judaism had become completely distinct religions.
