Abstract: 3-Spiropiperidino indolenines have been synthesized via novel Lewis acid-catalyzed SN2-type ring opening of activated aziridines with 1H-indoles followed by Pd-catalyzed dearomative spirocyclization with propargyl carbonates in up to 88% yields. The step and pot-economic transformation… read more here.

DOI: 10.1364/ao.457490
Abstract: The waveguide-type ring resonator (WRR) is the key rotation-sensing element in a resonant micro-optic gyroscope (RMOG). A universal model used to analyze both the polarization characteristics of the WRR and corresponding temperature-related polarization error in… read more here.
