Yield:-
Reaction Conditions:
with 4-methylmorpholine N-oxide;silica gel in dichloromethane;
Steps:
8.B Hex-4-yn-3-one
Step B Hex-4-yn-3-one A mixture of 24 g (0.25 mol) of (+-)-hex-4-yn-3-ol (from Step A), 40 g (0.34 mol) of N-methylmorpholine N-oxide and 75 g of 4 A molecular sieves in 250 mL of CH2Cl2 at 0° C. was treated with 2 g (5.7 mmol) of tetrapropylammonium perruthenate. The resulting mixture was warmed to rt and stirred for 1 h. The mixture was filtered through a pad of 400 g of silica gel; the flask and pad were rinsed well with CH2Cl2 (400 mL). The filtrate was concentrated. Distillation at reduced pressure (45 mmHg) afforded the title compound, bp=70-75° C.
