  Expeditious route to F unit building block of moenomycin A

  摘要：

  Synthesis of the versatile F sugar unit building block of moenomycin A, Phenyl 2-O-levulinoyl-4-C-methyl-1-thio-beta-D-glucopyranosiduronic acid is described starting from phenyl 1-thio-beta-D-galactopyranoside. The key synthetic steps included: (I) Regioselective protection of the 3-OH group of phenyl 6-O-trityl-1-thio-beta-D-galactopyranoside as its TBDMS ether, (ii) TBAF mediated TBDMS group migration from the C-3 to C-2 position of phenyl 3-O-TBDMS-4-C-methyl-6-O-trityl-1-thio-beta-D-galactopyranoside, and (iii) Selective deprotection of TBDMS and trityl groups in phenyl 2-O-levulinoyl-3-O-TBDMS-4-C-methyl-6-O-trityl-1 -thio-beta-D-glucopyranoside by DDQ.
