We subsequently turned our attention to check efficiency of methodology with N-substituted indolylidenecyanoacetate derivatives. Derivatives with simple alkyl chain like, Nmethyl, N-ethyl, N-propyl, N-butyl, N-pentyl, N-hexyl, N-heptyl, N-octyl, N-Dodecyl offered up to 80% yield of corresponding product (4Ba-4Bi). After simple alkyl group we checked branched alkyl substituents like N-isopropyl and N-cyclopentyl both gave corresponding product in high yield with single diastereomer (4Bj and 4Bk). Indolylidenecyanoacetates with Nmethoxy ethane group gave corresponding product in high yield 4Bl. We next explore N-substituted indolylidenecyanoacetates containing ester groups, these groups well tolerated in the reaction and offered corresponding product (4Bm-4Bn) in high yield. Indolylidenecyanoacetates with N-methyl and N-isopropyl group with different substituted group on aromatic ring also transformed to corresponding products (4Bo-4Bv) in high yield with single diastereomer. Further we checked efficiency of methodology with nitroethane derivative. We achieved product with good yield and poor diastereoselectivity (4Ca). Furthermore, we also tried substrate with methyl ester derivative which also works well with high yield and single diastereomer (4Da).
