New approach to 3-oxo-4-aza-5α-androst-1-ene-17β-(--butylcarboxamide)
摘要:
We describe the synthesis of 3-oxo-4-aza-5 alpha-androst-1-ene-17 beta-(N-tert-butylcarboxamide) (finasteride) from 4-androstene-3,17-dione (AD) in seven steps in an overall yield of 18.6% via oxidation, ammoniumation, dehydration, and dehydrogenation. (c) 2005 Elsevier Inc. All rights reserved.
