Chen, Qinfang published the artcileConstruct indeno[1,2-b]oxepine or cis-cyclopropylacrylate by sulfur ylides, Recommanded Product: 2,3-Dimethoxybenzaldehyde, the main research area is indenooxepine preparation; malononitrile aldehyde crotonate derived sulfur ylide annulation; cyclopropyl acrylate diastereoselective preparation; arylideneindenedione aldehyde crotonate derived sulfur ylide annulation.
For the first time, the [4 + 3] or [2 + 1] annulation of crotonate-derived sulfur ylides with arylidenemalononitrile or arylidene-1H-indene-1,3(2H)-dione was reported using Na2CO3 as the base. This protocol was advantageous as it does not require prior preparation of arylidenemalononitrile or arylidene-1H-indene-1,3(2H)-dione substrates, due to the independent participation of the base in the two reactions. This mild, operationally multicomponent process could be employed for the transformation of a wide variety of com. available aldehydes into the corresponding indeno[1,2-b]oxepines I [R = H, 4-CNC6H4, 2-OMeC6H4, etc.; R1 = Me, Et] or cyclopropyl acrylate core II in moderate to excellent yields under mild conditions.
