5-alkyldihydroorotic acids with Lawesson'sreagent followed by subsequent de-protection. The corresponding cisisomers were prepared by reduction of 5-alkyl-6-thioxoorotic acids with zinc in acetic acid. The stability and exchange reactions of 12a-c under physiological conditions were investigated by ultra-violet and 1H nmr spectroscopy. The attempted synthesis of 16, a fused cyclopentyl derivative of 3
