From a stand-up perspective you could either;
1. Step in & clinch or knee then clinch.
2. Create adequate space & sweep him - which is usually what I opt for - ashi barai works well in situations like this - usually when someone is charging at you, their legs imo are the weak spot - even a well timed inside leg kick would be enough to put them off-balance.
3. Use lateral/circular movement like alot of guys have mentioned - stops guys who want to close the distance & counter.
4. Lead him into a well timed counter - which would also be something I'd opt for - since he's already got some momentum, defensively if you get it right, it would be hard for your opponent to avoid your strike because of the momentum he's generated - usually anything that comes under the guard is usually well-advised - me personally would probably be a mae geri (front kick), a parry followed by a straight - something Machida is quite fond of or a do-mawashi kaiten geri (wheel kick) a la Kyokushin style.
5. If your a dirty fighter kick him in the groin & say it was an accident....
You have some interesting alternatives. They are especially important to me because so much of the karate kumite exercises omit or don't address this scenario, despite the boxer being well-apprised of it's likelihood....

I have had one really nasty experience with a golden=gloves trained boxer (not themselves a golden gloves champion). Here's what, how I would compare your alternatives, some of which because of my traditional karate background I didn't think of....
No. 1. My GG-trained boxer opponent was moving very defty with footwork.... This assumes he's going to remain still... No so in my case....
No. 2. Tang Soo Do free sparring prohibits grappling or strikes below the waist.... Self defense, I say great ideas....
No. 3. My opponent was not really pressuring me. The approach was really what seemed to me excellent footwork mobility of moving in & out of striking range, landing body shot flurries then retreating selecting when & how to move in again very agile-like.... Never saw any flat-footed, hesitation (until later).
^^^ I given the quick movements in, you didn't have much time to react.
^^^ In my case, however, my traditional karate philosophy also came into play....
I don't generally retreat and don't like to do so.... However in this case, with the continued success of the GG-trained boxer, after several successful sorties on their part, I did then retreat....
^^^ The later, however, only buys temporary time.... since you have lost the fight to that point, and re-engagement absent corrective action--just brings more of the same.... :icon_sad:
No. 4.
HA! HA!... Now it's my turn to Scoff.... Someone who is this good and highly agile in their mobility.... they're going to pummel you for sure until you get that shot off.... I don't see how you can "Lead" someone this good into anything.... I know when I getting hit multiple times by a moving target in a seconds time frame they've already won the exchange....
^^^ This is always given (by MMA'rs) as a reason why boxing is necessary to become a top striker.... karate's formal techniques are too choreographed to work against a case like the "flurries."
No. 5. Apparently, striking forum members will warm to this approach... Not something that addresses my failing to win a karate sparring match....
^^^ I ultimately won this match, but it took some soul searching....
