合成路线1
该中间体在本合成路线中的序号：(XXX)Alcohol (XXIX) was converted to the corresponding tosylate (XXX) employing p-toluenesulfonyl chloride and pyridine. Replacement of the pivaloyl protecting group of (XXX) for a mono-methoxytrityl group, yielding (XXXII), was effected by reductive cleavage of the pivaloyl ester of (XXX) and then treatment of alcohol (XXXI) with methoxytrityl chloride. Displacement of the tosylate group of (XXXII) by NaI in refluxing acetone provided the alkyl iodide (XXXIII).
