, p. 7829 - 7837 (2011/10/12)
An efficient approach to trans-4-hydroxylpyrrolidine lactams 1 starting from amino acid is described. The utility of this method has been demonstrated in the synthesis of antipsychotic nemonapride 3 and antiangiogenic streptopyrrolidine 4. Compared four s

Page/Page column 119-120, (2010/11/25)
A compound represented by the formula (I) or a salt thereof: (I) wherein the ring A represents a 5- to 8-membered ring which may have additional substituent besides R6, R7 and R8; R1 represents an electron-attracting group; R2, R3, R4 and R5 independently represent a hydrogen atom, a halogen atom, a group attached through a carbon atom, a group attached through a nitrogen atom, a group attached through an oxygen group, or a group attached through a sulfur atom; R6 represents a halogen atom, a group attached through a carbon atom, a group attached through a nitrogen atom, a group attached through an oxygen group, or a group attached through a sulfur atom, and R7 represents a cyano group, a nitro group, an acyl group which may have a substituent, a carboxyl group which may be esterified or amidated, or a hydrocarbon group which may have a substituent, or R6 and R7 together with a carbon atom to which they are attached may form a ring which may have a substituent; and R8 represents a hydrogen atom, a halogen atom, a group attached through a carbon atom, a group attached through an oxygen atom, or a group attached through a sulfur atom. The compound or salt has an excellent androgen receptor modulating effect, and is useful for the prevention/treatment of hypogonadism, partial androgen deficiency in aging male, decline in physical strength, cachexia, osteoporosis and the like.
