N-Methylpiperidine assisted catalytic multicomponent reaction
Keshtegar, Zahra,Heydari, Reza,Samzadeh-Kermani, Alireza
, p. 213 - 222 (2020)
Abstract: A catalytic methodology involving terminal alkynes, elemental sulfur, and three-membered heterocycles has been described. This domino transformation serves as a useful method for the synthesis of oxathiolane and thiazolidine derivatives from the readily available starting materials. In situ generated copper acetylides reacted with elemental sulfur and oxiranes or aziridines in the presence of N-methylpiperidine as sulfur activating agent to form synthetically important heterocycles.

Cerium(IV) catalysis: Efficient conversion of epoxides to thiiranes
Iranpoor,Kazemi
, p. 821 - 822 (1996)
Cerium(IV) as ceric ammonium nitrate (CAN), catalyzes the conversion of different epoxides to their corresponding thiiranes in excellent yields. The reaction occurs efficiently in the presence of ammonium thiocyanate in tert-butanol at room temperature.

Poly(amidoamine)s (PAMAMs) of high-generations (G > 5) exhibit high efficacy in gene transfection, but their high cost and severe cytotoxicity limit their use in biomedicine. In contrast, PAMAMs of low-generations (G w = 3500 Da) via disulfide bonds. This amphiphilic conjugate can self-assemble into stable nanomicelles. The results show that the obtained nanomicelles have a high zeta potential, which can condense DNA tightly. Moreover, the DNA/nanomicelle polyplexes can be fully dissociated by intracellular ROS and easily release the entrapped DNA. As gene vectors, the nanomicelles exhibited high transfection efficacy and fairly low cytotoxicity in vitro.
