Treatment of 1--2-pyrrolidinecarbaldehyde with sodium hydride in tetrahydrofuran (THF) gave the aldol condensation product, 5,6,7,7a-tetrahydro-2-methylthio-3H-pyrrolizin-3-one.However, when the same aldehyde was treated with sodium hydroxide in aqueous THF, 5,6,7,7a-tetrahydro-7a-hydroxy-3-methylthio-3H-pyrrolizin-3-one was obtained.These reactions were applied to the synthesis of indolizidine and pyrroloindole derivatives.

A series of novel indoline-(thio)urea were designed and prepared using indoline(s) as a new platform and tested as organocatalysts in the Michael and Morita–Baylis–Hillman reactions. Most of the compounds were found to be very active catalysts although they did not promote the enantioselectivity. As agents for the conversion of thiocarbonyl compounds into carbonyl compounds, potentials of PIFA and DDQ were also displayed. Furthermore, DFT calculations rationalized the experimentally observed non-enantioselectivity of the catalysts.
Enantioselective Synthesis of 2-Bromomethyl Indolines via BINAP(S)-Catalyzed Bromoaminocyclization of Allyl Aniline

An enantioselective bromoamination of allyl aniline with N-bromosuccinimide (NBS) catalyzed by BINAP(S) (BINAP monosulfide) is described. This protocol could provide a range of chiral 2-bromomethyl indolines in good to excellent yields with up to 87% ee.
