Reddy, Karla Janardhan | Kuilya, Tapan Kumar | Cha, Jin Kun
Stereochemical communication in homopropargylation and homoallylation of aldehydes was achieved by the Ti–O temporary linker strategy. Propargylic and allylic alcohol derivatives were employed as convenient pronucleophiles, obviating prefabrication of propargylation/allylation reagents. It was surprising that 1,6-diastereoselectivity was affected by not only the Grignard reagent but also the reaction solvent.
