Extracts of the male oil palm bunch moths, Tirathaba mundella Walker (Lepidoptera Pyralidae), were shown to contain four compounds namely, 5S, 65)-2,2,6-trimethyl-6-vinyl-tetrahydro-pyran-3-ol, 4-hydroxy-3-methoxy benzaldehyde (vanillin), 6,10,l4-trimethyl-2-pentadecanone, and the corresponding alcohol 6,10,l4-trimethyl-2-pentadecanol, which elicited responses from the females. However, when synthetic compounds were used in lures, the ketone and alcohol by themselves did not attract females, suggesting that they might not be an essential part of the blend. This can only be confirmed once their absolute configuration has been determined and the proper stereoisomers tested in the... [Pg.299]

In the area of pheromone synthesis, oxymercuration-oxidative demercuration has also proven valuable. For example, all four stereoisomers (rf tetrahydro-2,2,6-trimethyi-2//-pyran-3-ol, from the eim bark beetle Pteleobius vittatus have been acquired by a sequence from (/ )- and (S)-sulcatol, which incorporates this mercury chemistry.

Few examples are reported for the cyclization of 5-alkenols to 2,3-disubstituted tetrahydro-2//-pyrans where the stereoselectivity depends on the nature of the allylic substituent. The cyclization of 4-methyl-5-hexen-l-ol (1), performed with phenylselenyl triflate in dichloromethane at — 78 "C, proceeds with low 1,2-asymmetric induction and the corresponding tetrahydro-2//-pyran 2 is recovered in 85% yield as a 66 34 (Ircms/cis) diastereomeric mixture19.

Previous work with A6-Tetrahydrocannabinol [(3R,4R) 6a,7,10,10a-tetrahydro-6,6,9-trimethyl-3-pentyl-6H-dibenzo[b,d]pyran-l -ol, hereinafter referred to as A6-THC], has indicated that derivatives of this compound may prove clinically useful. The 7-carboxy derivative of A6-THC [A6-THC-7-oic acid] has been reported to be a non-psychoactive, potent antagonist to endogenous platelet activating factor and, thus, a useful treatment for PAF-induced disorders, such as asthma, systemic anaphylaxis, and septic shock. (U.S. Pat. No. 4,973,603, issued Nov. 27, 1990 to Sumner Burstein). Another derivative, (3S,4S)-7-hydroxy-A6-THC-l,l-dimethylheptyl, has been reported to possess analgesic and antiemetic activities.

Compounds 100 and 101 also react with 2-aminothiophenol, forming 3-(2,2,3-2H-benzothiazolyl)-2-(trifluoromethyl)tetrahydrofuran-2-ol and 3-(2,2,3-2//-benzothia-zolyl)-2-(trilluoromethyl)tetrahydro-2//-pyran-2-ol, respectively (Scheme 109). The structure of the latter is confirmed by X-ray analysis (00T7267). [Pg.327]
