摘要: The present invention is directed to a process for the preparation of a compound of formula (X-a) or a pharmaceutically acceptable salt form thereof, wherein: R1 is selected from the group consisting of: C1-5 alkyl substituted with 0-5 R1a, —(CH2)r—C3-10 cycloalkyl substituted with 0-5 R1a, and —(CH2)r-aryl substituted with 0-5 R1a. Compounds of Formula (X-a) are macrocyclic molecules containing anti-succinate residues which inhibit metalloproteinases such as aggrecanase, and the production of tumor necrosis factor (TNF). The anti-succinates are formed by an Ireland Claisen rearrangement of a silyl ketene acetal which proceeds with high stereoselectivity.
