Yield:35362-83-5 0.45 g
Reaction Conditions:
with acetamide;[bis(acetoxy)iodo]benzene in methanol at 20; for 16 h;
Steps:
97.1 Step 1: Synthesis of Ethyl(imino)(methyl)-λ 6-oxosulfane (Intermediate 97-2)
The starting material (97-1) (1.0 g) was dissolved in methanol (5 ml), then CH 3 COONH 2 (2.024 g) and diacetoxyiodobenzene (10.57 g) were added, and the reaction was stirred at room temperature for 16 hours. The reaction was complete as detected by LCMS. The reaction solution was directly rotated to dryness, and was separated and purified by silica gel column chromatography (petroleum ether/ethyl acetate=5:1) to obtain intermediate 97-2 (0.45 g).
