Technology Process of spiro

There total 1 articles about spiro which guide to synthetic route it. The literature collected by LookChem mainly comes from the sharing of users and the free literature resources found by Internet computing technology. We keep the original model of the professional version of literature to make it easier and faster for users to retrieve and use. At the same time, we analyze and calculate the most feasible synthesis route with the highest yield for your reference as below:

synthetic route:

Reference yield: 100.0%

N-fluorenylidene methylamine N-oxide (33226-81-2) + phenylpropynoic acid ethyl ester (2216-94-6) → spiro (139286-66-1)

Guidance literature:

In tetrahydrofuran; at 40 ℃; for 6h;

DOI:10.1016/S0040-4020(01)80585-8

Reference yield: 98.0%

spiro (139286-66-1) + methyl iodide (74-88-4) → Ethyl 2-benzoyl-(9-fluorenyliden)acetate (139286-80-9)

Guidance literature:

In tetrahydrofuran; at 40 ℃; for 72h;

DOI:10.1016/S0040-4020(01)80585-8

upstream raw materials:

N-fluorenylidene methylamine N-oxide

phenylpropynoic acid ethyl ester

Downstream raw materials:

Ethyl 2-benzoyl-(9-fluorenyliden)acetate
