Bowden, Kenneth published the artcileThe synthesis of some compounds related to muscarine, SDS of cas: 27943-46-0, the publication is Journal of the Chemical Society, Perkin Transactions 1: Organic and Bio-Organic Chemistry (1972-1999) (1978), 1493-504, database is CAplus.
New compounds related to muscarine (I) were prepared by cyclization of aminoacetylenic glycols, themselves prepared by condensation of novel aminoacetaldehyde hemiacetal salts with alkynol derivatives E.g., Me2N+HCH2CH(OH)(OEt) Cl– with PhCH2OCMe2CCH gave 13-16% PhCH2OCMe2CCCH(OH)CH2NMe2, which with HgSO4/H2SO4 gave 15% THF derivative II.
Journal of the Chemical Society, Perkin Transactions 1: Organic and Bio-Organic Chemistry (1972-1999) published new progress about 27943-46-0. 27943-46-0 belongs to tetrahydropyran, auxiliary class Tetrahydropyran,Alkynyl,Ether, name is 2-((2-Methylbut-3-yn-2-yl)oxy)tetrahydro-2H-pyran, and the molecular formula is C10H16O2, SDS of cas: 27943-46-0.
