Abstract
Pyrido[1,2-a]indoles are known as medicinally and pharmaceutically important compounds, but there is a lack of efficient methods for their synthesis. We report a convenient and efficient route to these privileged structures starting from easily accessible 2-substituted pyridines and aryne precursors. A small library of compounds has been synthesized utilizing the developed method, affording variously substituted pyrido[1,2-a]indoles in moderate to good yields.

Abstract
In this article, we address the presence of the prekinamycin quinone methide using the techniques of spectral global fitting and the 13C-labeling of the reactive centre. Two-electron reduction of a prekinamycin affords a long-lived quinone methide species that was characterised spectrally. A correlation was made between the calculated DeltaE (kcal/mol) values for quinone methide tautomerisation and cytostatic activity to support the postulate that the quinone methide plays a role in prekinamycin biological activity. We also prepared a stable quinone methide of prekinamycin and studied its solution chemistry directly.
