Abstract: 5-, 6- or 7-Membered fully saturated 1-azacarbocyclic-2-ylidene derivatives of guanidine having anti-secretory and hypoglycemic activities, and further useful for treatment of cardiovascular disease states.

Abstract: A method for reducing indole compounds to the corresponding indoline compounds substantially free of undesirable side reactions is described. The method involves contacting an indole compound with a borane complex reagent in the presence of trifluoroacetic acid. The method is rapidly and readily carried out and provides an excellent method for preparing certain indoline compounds from the corresponding indole compounds. A novel dioxyborane useful as a borane reagent is also disclosed.
