Novel derivatives of 3α,7α-dihydroxy-5β-cholan-24-OIC acid (chenodeoxycholic acid) and 3α,7β-dihydroxy-5β-cholan-24-OIC acid (ursodeoxycholic acid)
摘要:
Several 7-acyl cheno- and ursodeoxycholic acids were obtained in good yields starting from the corresponding cheno- and ursodeoxycholic acids, by a diacylation-selective hydrolysis procedure. A superior method for the synthesis of the 7-oleyl derivatives, by a selective acylation procedure, is also presented.
