Synthesis and mannosidase inhibitory activity of 6- and 7-substituted analogs of swainsonine
摘要:
Swainsonine (1), an inhibitor of the important glycoprotein-processing enzyme Golgi alpha -mannosidase II, is a clinical candidate for cancer treatment. Analogs bearing substituents at C-6 and C-7 have been prepared and evaluated as inhibitors of alpha -mannosidase (jack bean), a closely related enzyme. (C) 2001 Published by Elsevier Science Ltd.
A novel one-pot procedure for the stereoselectivesynthesis of α-hydroxy estersfrom ortho esters was developed. Key steps were multi-heteroatom Cope rearrangements of O-acylated N-hydroxy-l-tert-leucinol-derived oxazoline N-oxides leading to α-acyloxy oxazolines and, after methanolysis, to the target molecules in 67−80% yield and 94−98% ee.
