Formation and utility of sulfonic acid protecting groups |
| abstract |
The present invention is a method of protecting a sulfonic acid functional group in an organic molecule as a substituted or unsubstituted neopentyl sulfonate ester. The method allows the conversion of R-SO3-H to R'-SO3-H, wherein R and R' are different organic radicals. Also disclosed is a method of increasing the bioavailability of drugs with a sulfonic acid functional group by protecting the sulfonic acid functional group as a substituted neopentyl sulfonate ester which has a masked heteroatom nucleophile. The masked nucleophile can be liberated in vivo, resulting in removal of the neopentyl protecting group and regeneration of the parent drug. |
