摘要
A facile, racemic synthesis of a 'twisted' transition-state analogue of biotin is described. A key reaction is the electronically assisted ring-closure of the sulfur containing ring by displacement of an in situ generated mesylate by a suitably positioned 4-methoxybenzyl sulfide. The crystal structure of tricyclic compound 6 shows the AB ring system to indeed be twisted. The 'twist' was introduced to examine the possible involvement of sulfur participation in biotin biochemistry. (C) 2003 Elsevier Ltd. All rights reserved.
