Synthesis of spiro ortho esters, spiro ortho carbonates, and intermediates |
| abstract |
Ortho esters and ortho carbonates can be produced by alkylating esters and carbonates with, for example, the hexafluorophosphate salt of a trialkyl oxonium ion. The spiro species are useful intermediates in the synthesis of complex organic molecules. Synthetic pathways for the production of medically active compounds incorporates spiro ortho esters. Anti-first-pass effect materials are produced in high yield utilizing a synthetic strategy incorporating cyclic ortho ester intermediates. |
