标 题 :Process for the synthesis of vitamin k2
发明人：SHASTRI MAYANK; BAIKAR MRUNALI H; VORA PARIN K; BNS RAJU
权利人:SYNERGIA LIFE SCIENCES PVT LTD
摘要:The present disclosure relates to the synthesis of Vitamin K2 bearing varying prenyl side chains. The synthesis comprises the reaction of phenyl sulfone of tert-butyl dimethyl silyl (TBDMS) protected mono prenyl menadiol with prenyl halides bearing varying prenyl units in the presence of the phase transfer catalyst followed by reductive desulphonation to yield TBDMS ether of Vitamin K2. The TBDMS ether is then oxidized in the presence of chromium trioxide and periodic acid to yield the corresponding Vitamin K2.
