New Synthon for the Convergent Construction of Skipped Conjugation Polyenes: Synthesis of Ethyl Docosa-4,7,10,13,16,19-hexaenoate
摘要:
The preparation and subsequent Wittig reaction of the (Z,Z)-phosphonium salt 4, a useful synthon for the preparation of skipped conjugation polyenes, are reported. Salt 4 is a key intermediate for the synthesis of ethyl docosa-4,7,10,13,16,19-hexaenoate (3b).
