markedly better than the typically applied hard enolization protocols for regioselective enoxysilane formation from unsymmetrical 3-substituted cycloalkanones. Five-, six-, and seven-membered cycloalkanones each with 3-methyl, 3-isopropyl, or 3-phenyl substituents were investigated, and in all but one case, regioselectivities were ≥11:1 for enolization away from the substituent. These results are complementary
