EFFECTIVE PRODUCTION PROCESS FOR MUGINEIC ACID COMPOUND

摘要

Disclosed is a process for producing a mugineic acid compound, which is s hown by the following scheme. STEP 1 STEP 2 STEP 3 STEP 4 wherein R1 and R2 independently represent a hydrogen atom or a hydroxyl group; R3 represents a hydroxyl group or an amino group; R4 and R7 independently represent a hydro gen atom or a protective group for a carboxyl group; R5 represents a protect ive group for an amino group; R6 represents a protective group for a carboxy l group; and R8 represents -OR9 (wherein R9 represents a protective group fo r a hydroxyl group) or -NHR10 (wherein R10 represents a protective group for an amino group)].
