DOI: 10.1021/acs.orglett.2c01974
Abstract: Two strategies are described en route to an enantioselective total synthesis of gelsenicine. One approach centers on a chirality transfer cycloisomerization that ultimately fell short. Separately, an asymmetric catalysis route utilizing bisphosphine-gold-catalyzed cycloisomerization was pursued.… read more here.

Abstract: Reinforcement learning (RL) agents learn by encouraging behaviors, which maximizes their total reward, usually provided by the environment. In many environments, however, the reward is provided after a series of actions rather than each single… read more here.
