Answer: Transplanting stress can certainly cause browning, shriveling leaves until the roots become established. Couple that with extreme heat and it's no wonder your new trees are looking puny! New growth on the branch tips is encouraging. It means your trees are strong and trying to make a come back. I'd continue to water them deeply once a week throughout the growing season to help the roots become firmly established in their new homes. I expect you'll see additional new growth the rest of the summer. I think your trees will recover and next spring when they leaf out they should look just fine. Don't give up on them yet!
Best wishes with your landscape!
