A process is described for the synthesis of diastereomeric 2-methyl-4-hydroxy-5-protected-hydroxy-hept-6-en-prolinolamides, which are useful as intermediates in the synthesis of the C₁₀-C₁₈ chain of the macrolide structure for the immunosuppressant FK-506. These compounds are also useful as intermediates for preparing lactone ultraviolet radiation absorbers.
