Referee A Comment:
--------------------
  "The authors describe highly enantio- and diastereo selective Michael reaction of aldehyde to nitroalkene catalyzed by originally developed diethylprolinol silyl ether catalyst 6 that possessed long alkyl chain at C4 position, as surfactant-type organocatalyst with formic acid as co-catalyst. The reaction is carried out in the presence of water, therefore it can be avoided environmental problems and applicable to large scale synthesis in industrial field. I shall decide whether to accept the manuscript after major revisions. Comments:

2. Author should employ alkyl substituted nitro alkene such as 1-nitrohex-1-ene in Table 2.3. Ref. 10 should be inserted to ¡°Reference and Note¡± in the text. (should not be supporting information).


--------------------
Referee B Comment:
--------------------

P1, right column, line 7-5: The author should give some comment on the result of increase in diastereoselctivity by lowering the catalyst loading.
